Description
The JW060 Triple-Output-Series P o wer Modules are dc-dc con v erters that operate over an input v oltage r ange
of 36 Vdc to 75 Vdc and pro vide three dc outputs . The outputs are fully isolated from the inputs, allo wing versa-
tile grounding connections. Built-in shielding provides improved EMI performance. The modules have a maxi-
mum power rating of 60 W at a typical full-load efficiency of 86%.
The total output power of the JW060 Triple-Output-Series Power Modules is limited to 60 W. The main output
(V
O1
) is tightly regulated and designed to deliver up to 45 W. The auxiliary outputs (V
O2
and V
O3
) are
cross-regulated and can provide a total of 58 W with the main output loaded at its minimum of 2 W.
The modules have a metal baseplate for excellent thermal performance in a small package . Threaded-through
holes are provided to allow easy mounting or addition of a heat sink for high-temperature applications. The
standard feature set includes output trim and remote on/off for convenient flexibility in distributed power appli-
cations.
The JW060 Triple-Output-Series P ower Modules use ad vanced,
surface-mount technology and deliver high-quality, efficient,
and compact dc-dc conversion.

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 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, dc fuse with a maximum rating of 20 A (see Saf ety Consider ations 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.

Design Considerations
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. For the test configuration in Figure 13, a 33 µF
electrolytic capacitor (ESR < 0.7 Ω at 100 kHz)
mounted close to the power module helps ensure sta-
bility of the unit. For other highly inductive source
impedances, consult the factory for further application
guidelines.

JW060 Triple-Output Series Power Modules: dc-dc Converters;
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
22.2-950, and EN60950.
For the converter output to be considered meeting the
requirements of saf ety extr a-low v oltage (SELV), one of
the following must be true:
■
All inputs are SELV and floating, with the output also
floating.
■
All inputs are SELV and grounded, with the output
also grounded.
■
Any non-SELV input must be provided with rein-
f orced insulation from an y other hazardous voltages,
including the ac mains, and must have a SELV reli-
ability test performed on it in combination with the
converters. Inputs must meet SELV requirements.
If the input meets extra-low voltage (ELV) require-
ments, then the converter’s output is considered ELV.
The input to these units is to be provided with a maxi-
mum 20 A normal-blow fuse in the ungrounded lead.
Assembly Considerations
The power module is not encapsulated. It is designed
to be mounted to the printed-wiring board (PWB) after
the assembly cleaning process.
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 exhibits foldback characteristics
(output current decrease). The unit operates normally
once the overload condition is removed.
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 ON/OFF pin, and off during a logic low.
Negative logic remote on/off turns the module off dur-
ing a logic high and on during a logic low.
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 16). A logic low is Von/off = 0 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 15 V. The maximum allowable
leakage current of the switch is 50 µA. It is not recom-
mended to drive the ON/OFF pin with an external
source; however, if one is used, current into the pin
must not exceed 1 mA.
If not using the remote on/off f eature , do one of the
following:
■F or negativ e logic , short ON/OFF pin to VI(–).
■For positive logic, leave ON/OFF pin open.

Output Voltage Set-Point Adjustment
(Trim)
Output voltage trim allows the user to increase or
decrease the output voltage set points of all outputs
simultaneously. This is accomplished by connecting an
external resistor between the TRIM pin and either the
VO1(+) or COM pins. With an external resistor between
the TRIM and COM pins (Radj-down), the output voltage
set points decrease (see Figure 17). The following
equation, plotted in Figure 18, gives the required exter-
nal-resistor value to lower the output voltages by a per-
centage (∆%).
With an e xternal resistor connected between the TRIM
and V O1(+) pins (Radj-up), the output voltage set points
increase (see Figure 19).
The following equation, plotted in Figure 20, gives the
required external-resistor value to raise the output volt-
ages by a percentage (∆%).
The voltage between the VO1(+) and COM terminals
must not exceed the minimum output overvoltage shut-
down v oltage as indicated in the F eature Specifications
table .
If not using the trim feature, leave the TRIM pin open.

Voltage
Output Overvoltage Protection
The output overvoltage clamp consists of circuitry that
monitors the voltage on the output terminals. If the volt-
age on the output terminals exceeds the overvoltage
protection threshold, then the module will shut down
and attempt to restart periodically.
Overtemperature Protection
To provide protection in a fault condition, the unit is
equipped with a temperature limiting circuit. This circuit
will not engage unless the unit is operated above the
absolute maximum temperature limit. When active, the
overtemperature circuit lowers all output voltages suffi-
ciently to prevent exceeding the overtemperature
threshold. Recovery from the temperature limit is auto-
matic after the unit cools below the overtemperature
threshold.
Thermal Considerations
Introduction
The power modules operate in a variety of thermal
environments; however, sufficient cooling should be
provided to help ensure reliable operation of the unit.
Heat-dissipating components inside the unit are ther-
mally coupled to the metal baseplate. Heat is removed
by conduction, convection, and radiation to the sur-
rounding environment. Proper cooling can be verified
by measuring the metal baseplate temperature. Peak
temperature (T
C
) occurs at the position indicated in
Figure 21.
8-716 (C).g
Note: Top view, pin locations are for reference.
Measurements shown in millimeters and (inches).
Figure 21. Case Temperature Measurement
Location
The temperature at this location should not exceed
100 °C. The output power of the module should not
exceed the rated power for the module as listed in the
Ordering Information table.
Although the maximum case temperature of the power
modules is 100 °C, you can limit this temperature to a
lower value for extremely high reliability.
Thermal performance of the module varies with the
direction of airflow, assumed to be parallel to one edge
of the baseplate. The best orientation has air entering
the side with input pins, and the second best orienta-
tion has air entering the side closest to the ON/OFF
and V
O3
(–) pins.

Introduction
(continued)
Total power dissipation for the modules at 48 V input is
given by Figure 24 and Figure 25. Power dissipation at
36 V input is approximately 0.3 W higher than shown
for 48 V input, and power dissipation at 75 V input is
approximately 0.6 W higher than shown for 48 V input.
Heat Transfer Without Heat Sinks
Increasing airflow over the module enhances the heat
transfer via convection. Figure 22 shows the maximum
power that can be dissipated by the module without
exceeding the maximum base plate temperature ver-
sus local ambient temperature (T
A
), for natural convec-
tion through 4 m/s (800 ft./min.) in transverse (better)
orientation, where the air flows parallel to the shorter
side.
Note that the natural convection condition was mea-
sured at 0.05 m/s to 0.1 m/s (10 ft./min. to 20 ft./min.);
however, systems in which these power modules may
be used typically generate natural convection airflow
rates of 0.3 m/s (60 ft./min.) due to other heat dissipat-
ing components in the system. The use of Figure 22
and Figure 23 is shown in the following example.
Example
What is the minimum airflow necessary for a
JW060ABK operating at nominal line, an output current
of 9 A on 5 V, 1.25 A on +12 V, and 0 A on –12 V, and a

Heat Transfer with Heat Sinks
The power modules have through-threaded, M3 x 0.5
mounting holes, which enab le heat sinks or cold plates
to attach to the module. The mounting torque must not
exceed 0.56 N-m (5 in.-lb.). For a screw attachment
from the pin side, the recommended hole size on the
customer’s PWB around the mounting holes is
0.130 ± 0.005 inches. If a larger hole is used, the
mounting torque from the pin side must not exceed
0.25 N-m (2.2 in.-lb.).
Thermal derating with heat sinks is expressed b y using
the ov er all thermal resistance of the module. Total mod-
ule thermal resistance (
θ
ca) is defined as the maximum
case temperature rise (
∆
T
C, max
) divided by the module
power dissipation (P
D
):
The location to measure case temperature (T
C
) is
shown in Figure 21. Case-to-ambient thermal resis-
tance vs. airflow is shown, for various heat sink config-
urations and heights, in Figure 26. These curves were
obtained by experimental testing of heat sinks, which
are offered in the product catalog.
8-1511 (C)
Figure 26. Case-to-Ambient Thermal Resistance
Curves; Either Orientation
These measured resistances are from 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 are gener-
ally lower than the resistance of the heat sink by itself.
The module used to collect the data in Figure 26 had a
thermal-conductive dry pad between the case and the
heat sink to minimize contact resistance. The use of
Figure 26 is shown in the following example.

Heat Transfer with Heat Sinks
(continued)
Example
If an 85 °C case temperature is desired, what is the
minimum airflow necessary? Assume the JW060ABK
module is operating at nominal line and an output cur-
rent of 9 A on 5 V, 1.25 A on +12 V, and 0 A on –12 V,
maximum ambient air temperature of 40 °C, and a heat
sink that is 0.25 inches.

I
= 54 V
I
O1
@ 5 V = 9 A
I
O2
@ +12 V = 1.25 A
I
O3 @ –12 V = 0 A
TA = 40 °C
TC = 85 °C
Heat sink = 0.25 in.
Determine PD by using Figure 24:
PD = 11.5 W
Then solve the following equation:
Use Figure 26 to determine air v elocity for the 0.25 inch
heat sink.
The minimum airflow necessary for the JW060ABK
module is 0.6 m/s (110 ft./min.).
Custom Heat Sinks
A more detailed model can be used to determine the
required thermal resistance of a heat sink to provide
necessary cooling. The total module resistance can be
separated into a resistance from case-to-sink (θcs) and
sink-to-ambient (θsa) shown below (Figure 27).
8-1304 (C)
Figure 27. Resistance from Case-to-Sink and
Sink-to-Ambient
For a managed interface using thermal grease or foils,
a value of θcs = 0.1 °C/W to 0.3 °C/W is typical. The
solution for heat sink resistance is:
This equation assumes that all dissipated power must
be shed by the heat sink. Depending on the user-
defined application environment, a more accurate
model, including heat transfer from the sides and bot-
tom of the module, can be used. This equation pro vides
a conservative estimate for such instances.
Layout Considerations
Copper paths must not be routed beneath the power
module mounting inserts, which are conductive and
connected together electrically. Furthermore, it is not
recommended that any copper paths be routed under-
neath or near the power module because they are
likely to pick up noise from the module.
F or impro v ed EMI performance, f ollo w the layout guide-
lines given in data sheet DS97-053EPS for the
FLTR100V10 filter module, or data sheet
DS96-215EPS for the FLTR100V20 filter module. For
best EMI performance, use either of these filter mod-
ules at the input of one or more power modules.
