Description
The JC030-Series Power Modules are dc-dc converters that operate over an input voltage range of 18 Vdc to
36 Vdc and provide precisely regulated 2 V, 5 V, 12 V, and 15 V outputs. The outputs are isolated from the
inputs, allowing versatile polarity configurations and grounding connections. The modules have maximum
power ratings of 30 W at a typical full-load efficiency of 81%.
The power modules feature remote on/off, output sense (both negative and positive leads), and output voltage
adjustment, which allows output voltage adjustment from 60% to 110% (80% to 110% for the JC030A-M and
JC030D-M) of the nominal output voltage. For disk-drive applications, the JC030B-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 with no external filtering.

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
fusing is not included; however, to achieve maximum safety and system protection, always 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.

Lineage Power 11
Design Considerations
Grounding Considerations
The power module has an isolated case ground pin.
The case is not connected internally allowing the user
flexibility in grounding.
Input Source Impedance
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.
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
requirements of the end-use safety agency standard,
i.e., UL 1950, CSA C22.2 No. 950-95, and VDE 0805
(EN60950, IEC950).
For the converter output to be considered meeting the
requirements of safety extra-low voltage (SELV), the
input must meet SELV requirements.
The power module has extra-low voltage (ELV) outputs
when all inputs are ELV.
The input to these units is to be provided with a maxi-
mum 5 A normal-blow fuse in the ungrounded lead.
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 either foldback or tai-
lout 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, device code
suffix “1,” turns the module off during a logic high and
on during a logic low. Standard modules provide posi-
tive logic remote on/off.
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
Figure 22). A logic low is Von/off = –0.7 V to 1.2 V. The
maximum Ion/off during 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.
CAUTION: To avoid damaging the power module or
external on/off circuit, the connection
between the VI(–) pin and the input
source 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 circuit.)

Feature Descriptions (continued)
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 0.5 V
The voltage between the VO(+) and VO(–) terminals
must not exceed the minimum output overvoltage shut-
down voltage as indicated in the Feature Specifications
table. This limit includes any increase in voltage due to
remote-sense compensation and output voltage set-
point adjustment (trim). See Figure 23.
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.

Single-Module Remote-Sense Operation
Output Voltage Adjustment
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), the output voltage
set point (VO, adj) decreases (see Figure 24). The fol-
lowing equation determines the required external resis-
tor value to obtain an output voltage change of %ý.
For example, 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 25). The following
equation determines the required external resistor
value to obtain an output voltage change of %ý.
For example, to increase the output voltage of the
JC030B by 5%, the external resistor value 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 JC030 Power Module family has a fixed current-
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.

Thermal Considerations (continued)
The JC030-Series Power Modules are designed to
operate in a variety of thermal environments. As with
any electronic component, sufficient cooling must be
provided to help ensure reliable operation. Heat-dissi-
pating components inside the module are thermally
coupled to the case to enable heat removal by conduc-
tion, convection, and radiation to the surrounding envi-
ronment.
The thermal data presented is based on measure-
ments taken in a wind tunnel. The test setup shown in
Figure 26 was used to collect data for Figures 31 and
32.
Note that the natural convection condition was mea-
sured at 0.05 ms–1 to 0.1 ms–1 (10 ft./min. to
20 ft./min.); however, systems in which these power
modules may be used typically generate natural con-
vection airflow rates of 0.3 ms–1 (60 ft./min.) due to
other heat dissipating components in the system.
The graphs in Figures 27 through 32 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.
Basic Thermal Performance
The JC030-Series power modules are built with a spe-
cially 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 tempera-
ture of 100 °C and measured in the test configuration
shown in Figure 26.
Forced Convection Cooling
To determine the necessary airflow, determine the
power dissipated by the unit for the particular applica-
tion. Figures 27 through 30 show typical power dissipa-
tion for those power modules over a range of output
currents. With the known power dissipation and a given
local ambient temperature, the appropriate airflow can
be chosen from the derating curves in Figure 31. For
example, if the unit dissipates 6.2 W, the minimum air-
flow in an 80 °C environment is 1.02 ms–1
(200 ft./min.).

Heat Sink Selection
Several heat sinks are available for these modules.
The case includes through threaded mounting holes
allowing 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 32 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 unit dissi-
pates 7 W of heat in an 80 °C environment with an air-
flow of 0.66 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 26.)
TA= inlet ambient temperature
(See Figure 26.)
PD= power dissipation
θ ð (100 – 80)/7
θ ð 2.9 °C/W
From Figure 32, the 1/2 inch high heat sink or greater

Figure 32. Case-to-Ambient Thermal Resistance
vs. Air Velocity Curves; Either
Orientation
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.
The thermal resistances shown in Figure 32 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 Figure 32 was taken with
a thermally conductive dry pad between the case and
the heat sink to minimize contact resistance (typically
0.1 °C/W to 0.3 °C/W).
