■Heat Radiation and Reliability
The reliability of an IC is highly dependent on its operating temper a-
ture. Design should pa y particular attention to ensuring ample space
for radiating heat.
Be sure to apply silicon grease to the IC bef ore attaching a heatsink,
and to secure it firmly to the heatsink.
Other impor tant items to be considered regarding heat radiation in-
clude air convection during operation.
■
Calculating Internal Power Dissipation (P
D
)
PD is given by the following formula:
PD=IO•[VIN(mean)–VO]
Determine the size of the heatsink according to the relationship be-
tween allowable power dissipation and ambient temperature.
■Setting DC Input Voltag e
The waveform of a DC input voltage is shown below.
When setting the DC input voltage, pay attention to the following:
●VIN(min) must be no less than the sum of output voltage and the
minimum voltage difference between the input and output.
●VIN(max) must be no more than the maximum rated DC input volt-
age.
■Heatsink Design
The maximum junction temperature Tj(max) given in the absolute maxi-
mum ratings is specific to each product type and must be strictly
observed. Thus, thermal design must consider the conditions of use
which affect the maximum power dissipation PD(max) and the maxi-
mum ambient temperature Ta(max).
To simplify thermal design, the relationship between these two pa-
rameters has been presented in a graph, the Ta-PD characteristic
graph. Thermal design should include these steps:
1. Obtain the maxim um ambient temperature Ta(max).
2. Obtain the maximum power dissipation PD(max).
3. Look for the intersection point on the Ta-PD characteristic graph
and determine the size of the heatsink.
The size of the heatsink has now been obtained. However, in actual
applications, a 10 to 20% derating f actor is introduced. Moreov er , the
heat dissipation capacity of a heatsink highly depends on how it is
mounted. Thus, it is recommended to measure the heatsink and case
temperature in the actual operating environment.
The Ta-PD characteristics for each product type are provided for ref-
erence purposes.

■Recommended Silicone Grease
●G746 SHINETSU CHEMICAL INDUSTRIES CO., LTD.
●YG6260 TOSHIBA SILICONE CO., LTD.
●SC102 DOW CORNING TORAY SILICONE CO., LTD.
Please select a silicone grease carefully since the oil in some g rease
can penetrate the product, which will result in an extremely short
product life.
■Others
• Devices can not be operated in parallel to increase current.
• An isolation type diode is provided from input to ground and also
from output to ground. These may be destroyed if the device is re-
v erse biased. In this case, use a diode with lo w VF to protect them.
■Rectifier Diodes for Power Supplies
To rectify the AC input using rectifier diodes in power supplies, use
any of the SANKEN rectifier diodes shown in the following list. (Use
axial type diodes in a center-tap or bridge configuration.)

1. Variable output voltage with a single external resistor
The output voltage ma y be increased b y inserting resistor REX between
terminals No.4 (sensing terminal) and No.3 (output terminal). The cur-
rent IREX flowing into terminal No .4 is 1mA (typ .), therefore the adjusted
output voltage VOUT is:
VO=V04+IREX•REX *V04: output voltage of SI-3000F series
However, the built-in resistor (between terminals No. 4 and No.1) is a
semiconductor resistor, which has approximately thermal character is-
tics of +0.2%/°C.
It is important to keep the thermal characteristics in mind when adjust-
ing the output voltage.
2. Variable output voltage with two external resistors
The output voltage may be increased by inserting resistors REX1 be-
tween terminals No.4 (sensing terminal) and No .3 (output terminal) and
REX2 between terminals No.4 and No.1 (ground terminal).
The current I4IN flowing into terminal No.4 is 1mA (typ.) so the thermal
characteristics may be improved compared to the method shown in 1
by setting the external current IREX1 at approximately 5 times the value
of I4IN (stability coefficient S=5).
The adjusted output voltage VOUT in this case is:
VO=V04+REX1•IREX1
IREX1=S•I4IN
The value of the external resistors may be obtained as follows:
REX1= VO-V04 REX2= V04
S•I4IN , (S-1)•I4IN
*V04: Output voltage of SI-3000F series
S: Stability coefficient of I4IN (may be set to any value)
Note: In the SI-3000F series, the output voltage increase can be ad-
justed as mentioned above. However, when the rise is set to ap-
proximately 10V compared to output voltage V04, the necessary
output current may not be obtained due to the S.O.A. protection
circuit in the SI-3000F series.

1. Variable output voltage with a single external resistor
The output voltage ma y be increased by inserting resistor REX between
terminals No.4 (sensing terminal) and No.3 (output terminal). The cur-
rent IREX flowing into terminal No.4 is 1mA (typ.)(SI-3033C:0.43mA (typ .)),
therefore the adjusted output voltage VOUT is:
VO=V04+IREX•REX *V04: output voltage of SI-3000C series
However, the built-in resistor (between terminals No. 4 and No.1) is a
semiconductor resistor, which has approximately thermal character is-
tics of +0.2%/°C.
It is important to keep the thermal characteristics in mind when adjust-
ing the output voltage.
2. Variable output voltage with two external resistors
The output voltage may be increased by inserting resistors REX1 be-
tween terminals No.4 (sensing terminal) and No .3 (output terminal) and
REX2 between terminals No.4 and No.1 (ground terminal).
The current I4IN flowing into terminal No.4 is 1mA (typ.)(SI-3033C:
0.43mA(typ.)) so the thermal characteristics may be improved compared
to the method shown in 1 by setting the external current IREX1 at ap-
proximately 5 times the value of I4IN (stability coefficient S=5).
The adjusted output voltage VOUT in this case is:
VO=V04+REX1•IREX1
IREX1=S•I4IN
The value of the external resistors may be obtained as follows:
REX1= VO-V04 REX2= V04
S•I4IN , (S-1)•I4IN
*V04: Output voltage of SI-3000C series
S: Stability coefficient of I4IN (may be set to any value)
Note: In the SI-3000C series, the output voltage increase can be ad-
justed as mentioned above. However, when the rise is set to ap-
proximately 10V compared to output voltage V04, the necessary
output current may not be obtained due to the S.O.A. protection
circuit in the SI-3000C series.

1. Variable output voltage with a single external resistor
The output voltage ma y be increased by inserting resistor REX between
ter minals No.4 (sensing terminal) and No.3 (output terminal). The cur-
rent IREX flowing into terminal No .4 is 1mA (typ.), theref ore the adjusted
output voltage VOUT is:
VO=V04+IREX•REX *V04: output voltage of SI-3000J series
However, the built-in resistor (between terminals No. 4 and No.1) is a
semiconductor resistor, which has approximately ther mal characteris-
tics of +0.2%/°C.
It is important to keep the thermal characteristics in mind when adjust-
ing the output voltage.
2. Variable output voltage with two external resistors
The output voltage may be increased by inserting resistors REX1 be-
tween terminals No.4 (sensing terminal) and No.3 (output terminal) and
REX2 between terminals No.4 and No.1 (ground terminal).
The current I4IN flowing into terminal No.4 is 1mA (typ.) so the thermal
characteristics may be improved compared to the method shown in 1
by setting the external current IREX1 at approximately 5 times the v alue
of I4IN (stability coefficient S=5).
The adjusted output voltage VOUT in this case is:
VO=V04+REX1•IREX1
IREX1=S•I4IN
The value of the external resistors may be obtained as follows:
REX1= VO-V04 REX2= V04
S•I4IN , (S-1)•I4IN
*V04: Output voltage of SI=3000J series
S: Stability coefficient of I4IN (may be set to any value)
Note: In the SI-3000J series, the output voltage increase can be ad-
justed as mentioned above. However, when the rise is set to ap-
proximately 10V compared to output voltage V04, the necessary
output current may not be obtained due to the S.O.A. protection
circuit in the SI-3000J series.

■Ta-PD Characteristics
■Standard External Circuit
C1: Oscillation prevention capacitor (approx. 0.33µF)
Connection to terminal No .2 must be made as short as pos-
sible.
C2: Output capacitor (47 to 100µF)
Connection to terminal No .1 must be made as short as pos-
sible.
D1: Protection diode (RM1Z)
Required for protection against re v erse biasing of input and
output.
Note 1: Connect a 47µF to 100µF capacitor to both sides of the
load if the wiring between the output terminal and the
load is long.
Note 2: An isolation type diode is pro vided from input to ground
and also from output to ground. These may be destroy ed
if the de vice is rev erse biased. In this case, use a diode
with low VF to protect them.
Note 3: The output voltage may not be adjusted by raising the
ground voltage (using a diode or resistor).

■Ta-PD Characteristics
■Standard External Circuit
C1: Oscillation prevention capacitor (approx. 0.33µF)
Connection to terminal No.4 must be made as shor t as
possible.
C2: Output capacitor (47 to 100µF)
Connection to terminal No.1 must be made as shor t as
possible.
D1: Protection diode (RM1Z)
Required for protection against reverse biasing of input
and output.
Note 1: Prevention of oscillation at low temperatures
At low temperatures , oscillation may occur unless an
output capacitor with good tanδ is used. Be sure to
connect a tantalum capacitor (approx. 10µF) in par-
allel with output capacitor C2.
Note 2: An isolation type diode is provided from input to
ground and also from output to ground. These may
be destroyed if the device is reverse biased. In this
case, use a diode with low VF to protect them.

External Variable Output Voltage Circuit
1. Variable output voltage with a single external resistor
The output voltage of the STR9000 series ma y be decreased by insert-
ing a resistor between terminals No.1 (output terminal) and No.2 (out-
put fine adjustment terminals). Alternatively, the output v oltage may be
increased by inserting a resistor between terminals No.2 and No.5
(ground terminal).
<Standard External Circuit>
2. Fine adjustment of output voltage
The output voltage may be finely adjusted by using terminals No .1, No.2
and No. 5 as shown in the following connections.
<Standard External Circuit>
Note: The fine adjustment range of output voltage f or the STR9000 se-
ries is ±0.5V max for STR9012 and +1.0V/-2.0V max for STR9015.
Adjustment exceeding these values may cause start-up errors.

■Heat Radiation and Reliability
The reliability of an IC is highly dependent on its operating tempera-
ture. Design should pay particular attention to ensuring ample space
for radiating heat.
Be sure to apply silicon grease to the IC before attaching a heatsink,
and to secure it firmly to the heatsink.
Other important items to be considered regarding heat radiation in-
clude air convection during operation.
The reliability of peripheral components such as capacitors and coils
is closely related to temperature. A high operating temperature may
reduce the service life. Exceeding the allowable temperature ma y burn
the coils or damage capacitors. It is impor tant to make sure that the
temperature of output smoothing coils and input/output capacitors do
not exceed their allowable levels during operation. Allow for variation
in the ratings of the coils and minimize heat emission as far as pos-
sible. (For peripheral components, refer to the user manuals.)
■Internal Power Dissipation
PD can be obtained from the following formula.
• With built-in flywheel diode:
(SI-8000L series, STR7000/7100 series)
PD=VO•IO (100 –1)
ηx
• With external flywheel diode:
(SAI series, SI-8000E series, SI-8000S series)
PD=VO•IO(100 –1)–VF•IO(1– VO )
ηxVIN
Efficiency ηx depends on the input/output conditions. The efficiency
characteristics of each product type are provided for reference pur-
poses.
VO: Output voltage
VIN : Input voltage
IO: Output current
ηx : Efficiency(%)
VF: Diode forward voltage
■Heatsink Design
The maximum junction temperature Tj(max) given in the absolute maxi-
mum ratings is specific to each product type and must be strictly
observ ed. Thus , thermal design must consider the conditions of use
which affect the maximum power dissipation PD(max) and the maxi-
mum ambient temperature Ta(max).
To simplify thermal design, the relationship between these two pa-
rameters has been presented in a graph, the Ta-PD characteristic
graph. Thermal design should include these steps:
1. Obtain the maximum ambient temperature Ta(max).
2. Obtain the maximum power dissipation PD(max).
3. Look for the intersection point on the Ta-PD characteristic graph
and determine the size of the heatsink.
The size of the heatsink has no w been obtained. Howe v er, in actual
applications, a 10 to 20% derating factor is introduced. Moreover,
the heat dissipation capacity of a heatsink highly depends on how it
is mounted. Thus, it is recommended to measure the heatsink and
case temperature in the actual operating environment.
The Ta-PD characteristics f or each product type are pro vided f or ref-
erence purposes.

Please select a silicone grease carefully since the oil in some g rease
can penetrate the product, which will result in an extremely short
product life.
■Others
• Parallel operation can not be performed for increasing current.
• This type IC regulators can not be used for boosting current and
raising voltage.

■Selecting External Components
1. Inductor L1
1) It must be suited for switching regulators.
Do not use inductors as noise filters as they generate excessive heat.
2) It must have the appropriate inductance value.
If the inductance is too small (150µH or lower), abnormal oscillation may occur causing operation problems in the overcurrent protection
circuit within the rated current range.
3) The rated current must be satisfied.
If the rated current is exceeded, magnetic saturation leads to overcurrent.
2. Capacitors C1 and C2
1) They must satisfy the withstand voltage and allowable ripple current.
Exceeding the ratings of these capacitors or using them without derating shortens their service lives and may also cause abnormal
oscillation of the IC.
2) C2 must be a low-impedance type capacitor.
A low-impedance type capacitor is recommended for C2 to ensure minimum ripple voltage and stable switching operation.
3. Diode D1
The Sanken SFPB54 diode is recommended for D1. If you intended to use an equivalent diode, be sure to use a Schottky Barrier diode and
make sure that the reverse voltage applied to terminal 2 of the IC does not exceed the value (–1V) given in the absolute maximum ratings. If
you use a f ast recov ery diode or any other diode, application of a rev erse voltage gener ated from the reco very or ON voltage of the diode may
damage the IC.
Application
Variable output voltage
Output voltage can be adjusted in the same way as SI-8000S in page 85.
■Example of Printed Circuit Board
a) For optimum operation, there must be only
one GND line originating from terminal 4
and each component must be connected
with the shortest possible wiring.
b) To prevent heating of the IC, it is best to
make the GND pattern as large as pos-
sible since the inter nal frame and termi-
nal 4 (GND) are connected to each other .
■Ta-PD Characteristics
The efficiency depends on the input v oltage and the out-
put current. Thus, obtain the value from the efficiency
graph on page 75 and substitute the percentage in the
formula above.

IO:Output current

■Selecting External Components
1. Inductor L1
1) It must be suited for switching regulators.
Do not use inductors as noise filters as they generate excessive heat.
2) It must have the appropriate inductance value.
If the inductance is too small (150µH or lower), abnormal oscillation may occur causing operation problems in the overcurrent protection
circuit within the rated current range.
3) The rated current must be satisfied.
If the rated current is exceeded, magnetic saturation leads to overcurrent.
2. Capacitors C1 and C2
1) They must satisfy the withstand voltage and allowable ripple current.
Exceeding the ratings of these capacitors or using them without derating shortens their service lives and may also cause abnormal
oscillation of the IC.
2) C2 must be a low-impedance type capacitor.
A low-impedance type capacitor is recommended for C2 to ensure minimum ripple voltage and stable switching operation.
3. Diode D1
The Sanken AK06 diode is recommended f or D1. If y ou intended to use an equiv alent diode, be sure to use a Schottky Barrier diode and make
sure that the rev erse v oltage applied to terminal 2 of the IC does not exceed the v alue (–1V) giv en in the absolute maximum rat ings. If y ou use
a fast reco very diode or any other diode , application of a rev erse v oltage generated from the recov ery or ON voltage of the diode ma y damage
the IC.
Application
Variable output voltage
Output voltage can be adjusted in the same way as SI-8000S in page 85.
The efficiency depends on the input v oltage and the out-
put current. Thus, obtain the value from the efficiency
graph on page 79 and substitute the percentage in the
formula above.

Caution
1. Selecting External Components
(1) Choke coil L1
To maintain the stable operation of the regulator, choke coil L1
should be selected appropriately.
When selecting choke coil L1, consider the following:
a) Suitable for a switching regulator
Do not use a coil as a noise filter because it generates e xcess
heat.
b) Appropriate inductance
The greater the inductance of the choke coil, the smaller the
output ripple voltage. However, the siz e of the coil increases
large as the inductance increases. If the inductance is low , a
greater peak current flows to the IC and loss increases . This
is not favorable for stable operation.
The standard external circuit shows ref erence inductance val-
ues suitable for stable operation. However, the appropr iate
inductance may also be calculated as follows:
L= (VIN–VO)•VO
∆IL•VIN•f
Where, deltaIL indicates the ripple current of the choke coil
that is roughly set as follows:
• If the working output current is close to the maximum rating
(3 A) of SI-8000S
Ripple current = output current × 0.2 to 0.3
• If the working output current is about 1.0A or less
Ripple current = output current × 0.3 to 0.4
c) Satisfying the rated current
The rated current of a choke coil must be greater than the
maximum load current. Note that the inductance decreases
drastically and an excess current flo ws if the load current ex-
ceeds the rated current of the coil.
d) Good DC current superposition characteristics
The current flowing through a chok e coil is a triangular wav e-
form current superimposed on a DC current equal to the load
current. The coil inductance decreases as the load current
increases. In general, the coil can be used until the induc-
tance drops to 50% of the rated v alue. Use this as the refer-
ence value f or selection.

e) Less noise
A drum-type open magnetic core coil can affect peripheral
circuits with noise because the flux passes outside the coil.
To avoid this problem, use a toroidal, EI, or EE type open
magnetic core coil.
●SI-8000S Series
(2) Input capacitor C1
Input capacitor C1 operates as a bypass capacitor in the input
circuit.
When selecting input capacitor C1, consider the following:
a) The breakdown voltage is higher than the maxim um input volt-
age.
b) Satisfies the allowable ripple current
Exceeding the ratings of this capacitor or using it without de-
rating ma y reduce its service lif e and also cause the regulator
to malfunction. Therefore, an input capacitor with a sufficient
margin should be selected. With the SI-8000S Series, the
eff ectiv e ripple current Irms flowing to the input capacitor can
be calculated approximately as follows:
Irms 1.2 × VO × IO
VIN
(3) Output capacitor C2
Output capacitor C2 operates as a smoothing capacitor f or switch-
ing output. The output ripple voltage from the regulator is deter-
mined by the product of the pulsating current part ∆IL (=C2 charge-
discharge current) of the choke coil current and the equivalent
series resistance ESR of the output capacitor C2.
Vrip=∆IL•C2ESR
Therefore, a capacitor of low equivalent series resistance ESR
should be selected to reduce the output ripple voltage. It is rec-
ommended to select a lo w-impedance capacitor intended for use
with s witching regulators as C2.
(4) Diode D1
Use a Schottky barrier diode for D1. If you use a general rectifier
diode or fast recover y diode, the IC may be damaged. (Sanken
RK46 recommended)
2. Notes on Pattern Design
(1) Large current line
Since a large current flows through the bold lines in the standard
external circuit make the pattern as wide and as short as pos-
sible.

(2) Input capacitor
Place the input capacitor C1 and output capacitor C2 as close to
the IC as possible. Since a large current flows through the lead
wires of the input and output capacitors to charge and discharge
them quickly, minimize the lead wire length. The pattern around
the capacitors should also be minimized.

1. Soft Start
Connecting a capacitor to terminal no. 5 permits a soft start at power-
on. Delay time Td and rise time Ts can roughly be calculated as
shown below. (However, the values may slightly var y in an actual
application.) If the capacitance of C3 is increased, it takes longer to
discharge C3 after VIN is turned off. Theref ore, it is recommended to
set the value within 10µF. When not using the soft start function,
keep terminal no. 5 open.
Td= 0.7×C3 (sec)

2. Output ON/OFF control
Output can be turned on and off by using the soft start terminals.
Set the soft start terminal voltage to VSSL (0.2V typ.) or less to stop
output. To switch the potential at the soft start ter minals, drive the
open collector of the transistor . Since the discharge current from C3
flows to the ON/OFF control transistor, limit the current for protec-
tion. The SS terminal is pulled up to the power supply in the IC and
no external voltage can be applied.

(3) Sensing terminal
Output voltage sensing terminal VOS should be connected as close
to output capacitor C2 as possible. If the terminal is far from the
capacitor, the decreasing regulation and increasing switching
ripple may result in abnormal oscillation.

The output voltage adjustment resistance REX is calculated
as follows:
REX= VO'–VS
IVS
VS: Set output voltage of product
VO' : Adjusted output voltage
IVS : Inflow current to Vs terminal
* The temperature characteristics of output voltage worsen because
the value REX is not compensated for temperature. The Vs value
fluctuates by up to ±20% depending on the IC product. Since the
output voltage fluctuates more, a semi-fixed resistor is necessary
for accur ate output v oltage adjustment. If Vs and REX are constant,
the range of output voltage fluctuation can be e xpressed as f ollows:
∆VO'(%)=±20• VO'–VS

∆VO':Adjusted output voltage

S:Stability factor
Bypassing the current to REX2 improv es the temperature charac-
teristics and voltage fluctuation ranges more than the method of
(1). Stability factor S indicates the ratio of REX1 to Vs terminal
inflow current. Increasing the S value improves the fluctuations
of the temperature characteristics and output voltage . (Usually 5
to 10)
If the Vs and REX v alues are constant, the output voltage fluctua-
tion range can be calculated as follows:
∆VO'(%)= ±20 • VO'–VS

■Standard External Circuit
■Notes of Pattern Design
1) Thick lines in the Standard External Circuit are lines through which a large current flows. Make these pattern lines as thick as possible.
2) Place capacitor C1 on the input side as closely as possible to terminals no.2 and no.4 of the STR7000/7100 series. C1 may be used in
combination with a smoothing capacitor for rectifying, b ut the abov e points must be taken into consideration. In cases where C1 is not provided
or it is placed too far from the terminals stated above, abnormal oscillation due to poorer transient response or increased ringing may occur.
3) Connect v oltage sensing terminal VO.S and GND as closely as possible to output capacitor C4 (a current of approximately 1mA flo ws into the
VO.S terminal). If they are placed too far from C4, abnormal oscillation due to decreased regulation or increased switching ripple may occur.
4) Connect current sensing terminal C.S and GND as closely as possible to the detection resistor Rs (a current of approximately 0.5mA flows
from the CS terminal).
If they are placed too far from Rs, a decrease of the overcurrent setting point due to the voltage drop in the pattern, or malfunction of the
protection circuit due to increased ringing may occur.

■Caution
1. A low-impedance capacitor suitable for switching applications must be used for the external capacitor and must be connected as close to the
IC as possible in order to assure low ripple voltage and stable switching operation.
2. The SI-8200L and 8300L series do not have a built-in overcurrent protection circuit. Thus, avoid shor t-circuit conditions that may cause an
overcurrent.
3. The SI-8300L series may not start up if the input voltage rises too rapidly.
Do not use the SI-8300L series in applications where the input terminal, pin6, is opened and closed directly in a state where the input v oltage
is already applied.
4. Terminals LIN and NC in the connection diagram must be left unconnected to other circuits.
5. The IC's metalic heatsink is electrically floating. Do not connect it to GND or any other circuit.
6. Since the SI-8200L and 8300L series hav e an open-package construction, they can only be used in specific en vironments. Verify the operating
environment and use the IC within the conditions indicated in the reliability data.

■Ta-PD Characteristics
■SI-8500L application circuit
Terminal no.2 is for soft start. Connecting a capacitor to the terminal
enables the soft start function. See page 85 for the f ormulas to calcu-
late delay time and rise time. Output can be turned on and off by
using the soft start terminal. To stop output, set the soft start terminal
voltage to VSSL (0.2V typ.) or less. To switch the potential of the soft
start terminal, drive the open collector of the transistor. Since the
discharge current from C3 flows to the ON/OFF control tr ansistor , limit
the current for protection. The SS terminal is pulled up to the power
supply in the IC and no external voltage can be applied.
■Caution
1. Allocation of Components
For the best oper ating environment, the ground should be a single g round line at the GND terminal (terminal 2 on the SI-8400L, terminal 3 on
the SI-8500L), and the wiring from C1 and C2 to ground should be as short as possible.
2. Capacitors C1 and C2
1) They must satisfy the breakdown voltage and allowable ripple current.
Exceeding the ratings of these capacitors or using them without derating shortens their service lives and may also cause abnormal
oscillation of the IC.
2) C2 must be a low-impedance type capacitor to ensure minimum ripple voltage and stable switching operation.
3) C3 (SI-8500L only) is a capacitor for soft start. When not using soft start, leave terminal 2 open. It is pulled up inside the IC.
3. Terminals LIN and NC in the connection diagram must be left unconnected to other circuits.
4. The IC's metalic heatsink is electrically floating. Do not connect it to GND or any other circuit.
5. Since the SI-8400L and 8500L series have an open-package construction, they can only be operated in specific environments. Verify the
operating environment and use the conditions indicated in the reliability data.

■Ta-PD Characteristics
■Caution
1. A lo w-impedance capacitor suitab le f or switching applications must be used f or the external capacitor and must be connected as close to the
IC as possible in order to assure low ripple voltage and stable switching operation.
2. The SI-881L/8911L series does not ha v e a built-in ov ercurrent protection circuit on terminal VO2(–5V). Thus , a void short-circuit conditions that
may cause an overcurrent.
3. Do not connect VIN(–) of SI-8811L to GND. The overcurrent protection circuit may not work if they are connected.
4. Terminals left unconnected in the connection diagram must not be connected to other circuits.
5. The IC's metallic heatsink is electrically floating. Do not connect it to GND or any other circuit.
6. Since the SI-8800L and 8900L series ha ve an open-pac kage construction, they can be operated in specific environments . Verify the operating
environment and use the IC within the conditions indicated in the reliability data.

Multi-Output Type - Application Note

■Heat Radiation and Reliability
The reliability of an IC is highly dependent on its operating tempera-
ture. Design should pa y particular attention to ensuring ample space
for radiating heat.
Be sure to apply silicon grease to the IC bef ore attaching a heatsink,
and to secure it firmly to the heatsink.
Other impor tant items to be considered regarding heat radiation in-
clude air convection during operation.
The reliability of peripheral components such as capacitors and coils
is closely related to temperature. A high operating temperature may
reduce the service life. Exceeding the allowable temperature may
burn the coils or damage capacitors. It is important to make sure that
the temperature of output smoothing coils and input/output capaci-
tors do not exceed their allowable levels during operation. Allow for
variation in the ratings of the coils and minimiz e heat emission as far
as possible . (For peripheral components, refer to the user manuals.)
■Heatsink Design
The maximum junction temperature Tj(max) given in the absolute maxi-
mum ratings is specific to each product type and must be strictly
observ ed. Thus, thermal design must consider the conditions of use
which affect the maximum power dissipation PD(max) and the maxi-
mum ambient temperature Ta(max).
To simplify thermal design, the relationship between these two pa-
rameters has been presented in a graph, the Ta-PD characteristic
graph. Thermal design should include these steps:
1. Obtain the maximum ambient temper ature Ta(max).
2. Obtain the maximum power dissipation PD(max).
3. OLook for the intersection point on the Ta-PD characteristic graph
and determine the size of the heatsink.
The size of the heatsink has now been obtained. However, in actual
applications, a 10 to 20% derating f actor is introduced. Moreov er , the
heat dissipation capacity of a heatsink highly depends on how it is
mounted. Thus, it is recommended to measure the heatsink and case
temperature in the actual operating environment.
The Ta-PD characteristics for each product type are provided for ref-
erence purposes.

■Selecting External Components
1. Inductors L1 and L2
(1) Suitable for switching regulators
Do not use a coil as a noise filter because it generates excess heat.
(2) Appropriate inductance
A low inductance may cause abnormal oscillation, or cause the overcurrent protection circuit to malfunction in the rated current range.
(3) Satisfying the rated current
Exceeding the rated current may generate an extremely high current to flow due to magnetic saturation.
2. Capacitors C1, C2, and C3
(1) Satisfy the breakdown voltage and allowable ripple current
Exceeding the ratings of these capacitors or using them without derating ma y shorten their service liv es and also cause abnormal oscillation.
(2) Low impedance (C2, and C3)
A low-impedance model is recommended f or C2 and C3 to reduce the ripple voltage and stabilize s witching. For stable operation throughout
the input voltage range, however, the DC equivalent series resistance (ESR) of C2 and C3 should be 0.1 ohm or less.
3. Capacitors C4 and C5
(1) C4 and C5 are soft-start capacitors.
■Selecting Ch2 Output Voltage
When the VO2Cont terminal voltage is set to 0.5V or less, the output voltage changes to the values sho wn below . To switch the potential at the VO2Cont
ter minal, drive the open collector of the transistor. No external voltage can be applied to the terminal. Leave the terminal open when not in use
because the terminal is already pulled up in the IC. When using terminal no. 9, short it to terminal no. 10.
( ): STA802M
■Soft Start ON/OFF Circuit
Terminal nos. 3 and 8 are soft start terminals. Connect a capacitor to the terminal to permit a soft start. Output can be turned on and off by using
the soft start terminals. Set the soft start terminal voltage to VSSL (0.15V) or less to stop the output. To switch the potential at the soft start terminals,
drive the open collector of the transistor. Since the discharge currents from C4 and C5 flow to the ON/OFF control transistor, limit the current for
protection. The SS terminal is pulled up to the power supply in the IC and no external voltage can be applied to the terminal.

■Selecting External components for dropper type regulator
Input capacitor (Approx. 47µF)
Output capacitor (Approx. 47 to 100µF)
●Low ESR capacitors are recommended for input and output when using them in low temperature conditions (0°C or less)
■Selecting External components for switching type regulator
Input capacitor (Approx. 100µF)
Output smoothing capacitor (Approx. 330µF)
●Input capacitor and output capacitor must satisfy allowable ripple current.
●Low ESR capacitors are recommended for reducing output ripple voltage.
●Low ESR capacitors are recommended for input and output when using them in low temperature conditions (0°C or less)
Choke coil (200µH when V O is 3.3V or 5V, 300µH when VO is not 3.3V or 5V)
●When its winding resistance is high, its efficiency may decrease and the rated value may not be achieved.
●Pay attention to heat from the choke coil due to magnetic saturation caused by overload, short circuit of load, etc. because the overcurrent
protection starting current is approx. 1A.
Flywheel diode (Sanken AK04 recommended)
●Use a Schottky barrier diode for D1, D2 and D3 and mak e sure that the rev erse voltage applied to SW output terminal does not e xceed the value
(–1V) given in the maximum ratings.
●If you use a f ast recov ery diode or any other diode , application of a reverse v oltage generated from the reco very or ON voltage of the diode ma y
damage the IC.

■Ta-PD Characteristics
■Standard External Circuit
*1 CIN : Input capacitor (Approx. 47µF)
This capacitor is required if the input line is inductive and in the case of long wiring.
*2 CO: Output capacitor (47 to 220µF)
*3 Cd: Delay setting capacitor (0.1µF or more)
Use Cd to set the dela y time (tDLY) from when a low VO level due to OCP operation is detected until a flag signal is output.
This prevents a rush current from causing malfunction.
Approximate calculation: tDLY (Cd × VDLYth)/IDLY[sec]
When using soft start on VIN or if CIN has a large capacitance, set tDLY long enough for the output voltage to rise sufficiently
Be sure to connect Cd and do not use it for other applications, such as short circuiting Cd.
*4 D1 to D4: Reverse biasing protection diode
This diode is required for protection against reverse biasing of the input and output.
*5 RFLG : Set this to limit the inflow current into the FLG terminal to 1mA or less.

■Calculating the internal dissipation
PD is calculated as follows:
PD=[IO1•(VIN-VO1)]+[IO2•(VIN-VO2)]+[IO3•(VIN-VO3)]+[IO4•(VIN-VO4)]+VIN•IG
■Estimating Tj by heat measurement
1. Measuring position: At the root of pin 13
2. Add the thermal resistance "θj-L" between the junction and pin 13 and the Pd product of each channel to the measured temperature.
θj-L is as follows : θj-L1:8°C/W, θj-L2:7°C/W, θj-L3:5°C/W, θj-L4:8°C/W
The calculation formula is as follows :Tj=θj-L1•Pd1+θj-L2•Pd2+θj-L3•Pd3+θj-L4•Pd4+T13pin
