Description
The JW030-Series Power Modules are dc-dc converters that operate over an input voltage range of 36 Vdc to
75 Vdc and provide precisely regulated outputs. The outputs are isolated from the inputs, allowing versatile
polarity configurations and grounding connections. The modules ha v e maximum power ratings of up to 30 W at
a typical full-load efficiency of up to 83%.
These power modules feature remote on/off, output sense (both negative and positive leads), and output volt-
age adjustment, which allows output voltage adjustment from 80% to 110% fo r the JW030A-M, D-M, F-M, G-M
and 60% to 110% for the JW030B-M, C-M of the nominal output voltage. For disk-drive applications, the
JW030B-M Power Module provides a motor-start surge current of 3 A. The modules are PC board-mountable
and encapsulated in metal cases. The modules are rated to full load at 100 °C case temperature. No external
filtering is required.

JW030-Series Power Modules:
Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are abso-
lute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess
of those given in the operations sections of the data sheet. Exposure to absolute maximum ratings for extended
periods can adversely affect device reliability.
Electrical Specifications
Unless otherwise indicated, specifications apply over all operating input voltage, resistive load, and temperature
conditions.
Table 1. Input Specifications
Fusing Considerations
CAUTION: This power module is not internally fused. An input line fuse must always be used.
This encapsulated power module can be used in a wide variety of applications, ranging from simple stand-alone
operation to an integrated part of a sophisticated power architecture. To preserve maximum flexibility, internal fus-
ing is not included; howe ver, to achiev e maximum safety and system protection, alwa ys use an input line fuse. The
safety agencies require a normal-blow fuse with a maximum rating of 5 A (see Safety Considerations section).
Based on the information provided in this data sheet on inrush energy and maximum dc input current, the same
type of fuse with a lower rating can be used. Refer to the fuse manufacturer’s data for further information.

Test Configurations
8-489(C)
Note: Input reflected-ripple current is measured with a simulated
source impedance of 12 µH. Capacitor CS offsets possible
battery impedance. Current is measured at the input of the
module.
Figure 20. Input Reflected-Ripple Test Setup
8-513(C)
Note:Use a 0.1 µF ceramic capacitor. Scope measurement should
be made using a BNC socket. Position the load between
50 mm and 75 mm (2 in. and 3 in.) from the module.
Figure 21. Peak-to-Peak Output Noise
Measurement Test Setup
8-749(C).a
Note:All measurements are taken at the module terminals. When
socketing, place Kelvin connections at module ter m inals to
avoid meas urement errors due to socket contact resistance.

Design Considerations
Grounding Considerations
The case is not connected internally allowing the user
flexibility in grounding.
Input Source Im pedance
The power module should be connected to a low ac-
impedance input source. Highly inductive source
impedances can affect the stability of the power mod-
ule. A 33 µF electrolytic capacitor (ESR < 0.7 ¾ at
100 kHz) mounted close to the power module helps
ensure stability of the unit. (See Figure 20.)
Safety Considerations
For safety-agency approval of the system in which the
power module is used, the power module must be
installed in compliance with the spacing and separation
requir eme nts of the end-u se sa fety agency stan dard,
i.e.,
UL
1950,
CSA
C22.2 No. 950-95, and VDE 0805
(EN60950, IEC950).
If the input source is non-SELV (ELV or a hazardous
voltage greater than 60 Vdc and less than or equal to
75 Vdc), f or the module's output to be considered
meeting the requirements of safety extra-low voltage
(SELV), all of the following must be true:
■The input source is to be provided with reinforced
insulation from any other hazardous voltages, includ-
ing the ac mains.
■One VI pin and one VO pin are to be grounded or
both the input and output pins are to be kept floa ting.
■The input pins of the module are not operator acces-
sible.
■Anothe r SELV reliabili ty tes t is conduc ted on the
whole system, as required by the safety agencies, on
the combination of supply source and the subject
module to verify that under a single fault, hazardous
voltages do not appear at the module's output.
Note: Do not ground either of the input pins of the
module without grounding one of the output
pins. This may allow a non-SELV voltage to

Feature Descriptions
Overcurrent Protection
To provide protection in a fault (output overload) condi-
tion, the unit is equipped with internal current-limiting
circuitry and can endure current limiting for an unlim-
ited duration. At the point of current-limit inception, the
unit shifts from voltage control to current control. If the
output voltage is pulled very low during a severe fault,
the current-limit circuit can exhibit eit her foldback or
tailout characteristics (output current decrease or
increase). The unit operates normally once the output
current is brought back into its specified range.
Remote On/Off
Two remote on/off options are available. Positive logic
remote on/off turns the module on during a logic-high
voltage on the REMOTE ON/OFF pin, and off during a
logic low . Negative logic remote on/off turns the module
off during a logic high and on during a logic low. Nega-
tive logic, device code suffix “1,” is the f actory-preferred
configuration.
To turn the power module on and off, the user must
supply a switch to control the voltage between the
on/off terminal and the VI(–) terminal (Von/off). The
switch can be an open collector or equivalent (see Fig-
ure 23). A logic low is Von/off = –0.7 V to 1.2 V, during
which the module is off. The maximum Ion/off dur i ng a
logic low is 1 mA. The switch should maintain a logic-
low voltage while sinking 1 mA.
During a logic high, the maximum Von/off generated by
the power module is 6 V. The maximum allowable leak-
age current of the switch at Von/off = 6 V is 50 µA.
The module has internal capacitance to reduce noise
at the ON/OFF pin. Additional capacitance is not gen-
erally needed and may degrade the start-up character-
istics of the module.
CA UTION: T o a void damaging the power module or
external on/off circuit, the connection
between the VI(–) pin and the input
sourc e must be made before or simulta-
neously to making a connection
between the ON/OFF pin and the input
source (either directly or through the
external on/off circ uit.)
8-720(C).h
Figure 23. Remote On/Off Implementation
Remote Sense
Remote sense minimizes the effects of distribution
losses by regulating the voltage at the remote-sense
connections. The voltage between the remote-sense
pins and the output terminals must not exceed the out-
put voltage sense range given in the Feature Specifica-
tions table, i.e.:
[VO(+) – VO(–)] – [SENSE(+ ) – SENSE ( –)] ð 0.2 V
The voltage between the VO(+) and VO(–) termi nal s
must not exceed the minimum output overvoltage shut-
down v oltage as indicated in the F eature Specifications
table. This limit includes any increase in voltage due to
remote-sense compensation and output voltage set-
point adjustment (trim). See Figure 24.
If not using the remote-sense feature to regulate the
output at the point of load, then connect SENSE(+) to
VO(+) and SENSE(–) to VO(–) at the module.

Output Voltage Set-Point Adjustment
(Trim)
Output voltage trim allows the user to increase or
decrease the output voltage set point of a module. This
is accomplished by connecting an external resistor
between the TRIM pin and either the SENSE(+) or
SENSE(–) pins. With an external resistor between the
TRIM and SENSE(–) pins (Radj-down), th e out put v ol tage
set point (V O, adj) decreases (see Figure 25). The follow-
ing equation determines the required external-resistor
value to obtain an output voltage change of %ý.
For e xample, to lower the output voltage by 30%, the
external resistor value must be:
With an external resistor connected between the TRIM
and SENSE(+) pins (Radj-up), the output voltage set
point (VO, adj) increases (see Figure 26). The following
equations determine the re qui red exter na l-resi s tor
value to obtain an output voltage change of %ý.
JW030A-M, B-M, C-M:
For e xample, to increase the output voltage of the
JW030B-M by 5%, the external resistor value must be:
JW030D-M, F-M, G-M:
For e xample, to increase the output voltage of the
JW030D-M by 5%, the external resistor must be:
The combination of the output voltage adjustment and
sense range and the output voltage given in the Fea-
ture Specifications table cannot exceed 110% of the
nominal output voltage between the VO(+) and VO(–)
terminals.
The JW030-Series Power Modules have a fixed cur-
rent-limit set point. Therefore, as the output voltage is
adjusted down, the available output power is reduced.
In addition, the minimum output current is a function of
the output voltage. As the output voltage is adjusted
down, the minimum required output current can
increase.

Output Overvoltage Protection
The output overvoltage clamp consists of control cir-
cuitry, independent of the primary regulation loop, that
monitors the voltage on the output terminals. The con-
trol loop of the clamp has a higher voltage set point
than the primary loop (see Feature Specifications
table). This provides a redundant voltage-control that
reduces the risk of output overvoltage.

JW030-Series Power Modules:
Thermal Considerations
The JW030-Series Power Modules are designed to operate in a variety of thermal environments. As with any elec-
tronic component, sufficient cooling must be provided to help ensure reliable operation. Heat-dissipating compo-
nents inside the module are thermally coupled to the case to enable heat removal b y conduction, convection, and
radiation to the surrounding environment.
The thermal data presented is based on measurements taken in a wind tunnel. The test setup shown in Figure 27
was used to collect data for Figure 34.
The graphs in Figures 28 through 33 provide general guidelines for use. Actual performance can vary depending
on the particular application environment. The maximum case temperature of 100 °C must not be exceeded.
8-1046(C)
Note: Dimensions are in millimeters and (inches).
Figure 27. Thermal Test Setup
Basic Thermal Performance
The JW030-Series Power Modules are constructed with a specially designed, heat spreading enclosure. As a
result, full-load operation in natural convection at 50 °C can be achieved without the use of an external heat sink.
Higher ambient temperatures can be sustained by increasing the airflow or by adding a heat sink. As stated, this
data is based on a maximum case temperature of 100 °C and measured in the test configuration shown in
Figure 27.

Forced Convection Cooling
To determine the necessary airflow, determine the
power dissipated by the unit for the particular applica-
tion. Figures 28 through 33 show typical power
dissipation for these power modules ov er a range of
output currents. With the known power dissipation and
a given local ambient temperature, the appropriate air-
flow can be chosen from the derating curves in Figure
34. For example, if the JW030A-M dissipates 6.2 W,
the minimum airflow in a 80 °C environment is 1 ms–1
(200 ft./min. ).

Heat Sink Selection
Sev eral heat sinks are available f or these modules. The
case includes through-threaded mounting holes allow-
ing attachment of heat sinks or cold plates from either
side of the module. The mounting torque must not
exceed 0.56 N-m (5 in./lb.).
Figure 35 shows the case-to-ambient thermal resis-
tance, θ (°C/W), for these modules. These curves can
be used to predict which heat sink will be needed for a
particular environment. For example, if the JW030A-M
dissipates 7 W of heat in an 80 °C en vironment with an
airflow of 0.7 ms–1 (130 ft./min.), the minimum heat
sink required can be determined as follows:
where: θ= module’s total thermal resistance
TC, max = case temperature (See Figure 27.)
TA= inlet ambient temperature
(See Figure 27.)

Figure 35. Case-to-Ambient Thermal Resistance
vs. Air Velocity Curves; Either

Although the previous example uses 100 °C as the
maximum case temperature, for extremely high reliabil-
ity applications, one can use a lower temperature for
TC, max.
It is importa nt to point out that the therm al resi sta nc es
shown in Figure 35 are for heat transfer from the sides
and bottom of the module as well as the top side with
the attached heat sink; therefore, the case-to-ambient
thermal resistances shown will generally be lower than
the resistance of the heat sink by itself . The data in Fig-
ure 35 wa s taken with a thermally conductive dry pad
between the case and the heat sink to minimize contact
resistanc e (typi c ally 0.1 °C/W to 0.3 °C/W).
