§
The JRW series provide up to 70A output current in an industry standard half brick, which makes it an ideal choice
for optimum space, high current and low voltage applications. The converter incorporates synchronous rectification
technology and innovative packaging techniques to achieve high efficiency reaching 91% at 3.3V full load. The ultra
high efficiency of this converter leads to lower power dissipation such that for most applications a heat sink is not
required. The output is fully isolated from the input, allowing versatile polarity configurations and grounding
connections. Built-in filtering for both input and output minimizes the need for external filtering.

Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratin gs can cause permanent damage to the device. These are
absolute 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 the device reliability.

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 standalone operation to an
integrated part of 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 time-delay fuse with a maximum rating of 20A (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 sheet for further information.

Test Configurations
Note: Measure input reflected-ripple current with a simulated source
inductance (LTEST) of 12 µH. Capacitor CS offsets possible battery
impedance. Measure current as shown above.
Figure 43. Input Reflected Ripple Current Test
Setup.
Note: Use a 1.0 µF ceramic capacitor and a 10 µF aluminum or
tantalum capacitor. Scope measurement should be made using a
BNC socket. Position the load between 51 mm and 76 mm (2 in. and
3 in.) from the module.

36-75Vdc Input; 1.2Vdc to 12Vdc Output
Design Considerations
Input Source Impedance
The power module should be connected to a low
ac-impedance source. A highly inductive source
impedance can affect the stability of the power
module. For the test configuration in Figure 43, a
100μF electrolytic capacitor (ESR< 0.7Ω at 100kHz),
mounted close to the power module helps ensure the
stability of the unit. Consult the factory for further
application guidelines.
Output Capacitance
High output current transient rate of change (high
di/dt) loads may require high values of output
capacitance to supply the instantaneous energy
requirement to the load. To minimize the output
voltage transient drop during this transient, low E.S.R.
(equivalent series resistance) capa cit ors may be
required, since a high E.S.R. will produce a
correspondingly higher voltage drop during the
current transient.
Output capacitance and load impedance interact with
the power module’s output voltage regulation control
system and may produce an ’unstable’ output
condition for the required values of capacitance and
E.S.R.. Minimum and maximum values of output
capacitance and of the capacitor’s assoc iate d E.S.R.
may be dictated, depending on the module’s control
system.
The process of determining the acceptable values of
capacitance and E.S.R. is complex and is loaddependant. Lineage Power provides Web-based tools
to assist the power module end-user in appraising
and adjusting the effect of various load conditions and
output capacitances on specific power modules for
various load conditions.
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* 60950-1 Recognized, CSA
Note: All measurements are taken at the module terminals. When socketing,
place Kelvin connections at module terminals to avoid measurement errors due
to socket contact resistance.
No. 60950-3-01 Certified, and EN 60950-1 (VDE‡

*Note: -60V dc nominal battery plants are not
available in the U.S. or Canada.
For all input voltages, other than DC MAINS, where
the input voltage is less than 60V dc, if the input
meets all of the requirements for SELV, then:
The output may be considered SELV. Output
voltages will remain within SELV limits even
with internally-generated non-SELV voltages.
Single component failure and fault tests were
performed in the power converters.
One pole of the input and one pole of the
output are to be grounded, or both circuits are
to be kept floating, to maintain the output
voltage to ground voltage within ELV or SELV
limits.
For all input sources, other than DC MAINS, where
the input voltage is between 60 and 75V dc
(Classified as TNV-2 in Europe), the following must
be meet, if the converter’s output is to be evaluated
for SELV:
The input source is to be provided with
reinforced insulation from any hazardous voltage,
including the ac mains.
One Vi pin and one Vo pin are to be reliably
earthed, or both the input and output pins are to
be kept floating.
Another SELV reliability test is conducted 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.
The power module has ELV (extra-low voltage)
outputs when all inputs are ELV.
All flammable materials used in the manufacturing of
these modules are rated 94V-0.
The input to these units is to be provided with a
maximum 20A fast-acting (or time-delay) fuse in the

Feature Descriptions
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
during a logic high and on during a logic low. Negative
logic, device code suffix "1," is the factory-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 Figure 46). A logic low is Von/off = 0
V to I.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 at
Von/off = 15V is 50 µA. If not using the remote on/off
feature, perform one of the following to turn the unit
on:
For negative logic, short ON/OFF pin to VI(-).
For positive logic: leave ON/OFF pin open.
Figure 46. Remote On/Off Implementation.
Overcurrent Protection
To provide protection in a fault output overload
condition, the module is equipped with internal
current-limiting circuitry and can endure current limit
for few seconds. If overcurrent persists for few
seconds, the module will shut down and remain latchoff. The overcurrent latch is reset by either cycling the
input power or by toggling the on/off pin for one
second. If the output overload condition still exists
when the module restarts, it will shut down again. This
operation will continue indefinitely until the
overcurrent condition is corrected.
An auto-restart option is also available.
Input Undervoltage Lockout
At input voltages below the input undervoltage lockout
limit, the module operation is disabled. The module
will begin to operate at an input voltage above the
undervoltage lockout turn-on thr eshold.
36-75Vdc Input; 1.2Vdc to 12Vdc Output
Overtemperature Protection
These modules feature an overtemperature protection
circuit to safeguard against thermal damage. The
circuit shuts down and latches off the module when
the maximum device reference temperature is
exceeded. The module can be restarted by cycling
the dc input power for at least one second or by
toggling the remote on/off signal for at least one
second.
Over Voltage Protection
The output overvoltage protection consists of circuitry
that monitors the voltage on the output terminals. If
the voltage on the output terminals exceeds the over
voltage protection threshold, then the module will
shutdown and latch off. The overvoltage latch is reset
by either cycling the input power for one second or by
toggling the on/off signal for one second. The
protection mechanism is such that the unit can
continue in this condition until the fault is cleared.
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
output voltage sense range given in the Feature
Specifications table i.e.:
[Vo(+) – Vo(-)] – [SENSE(+) – SENSE(-)] ≤ 10% of
.
V
o,nom
The voltage between the Vo(+) and Vo(-) terminals
must not exceed the minimum output overvoltage
shut-down value 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
47. 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.
Although the output voltage can be increased by both
the remote sense and by the trim, the maximum
increase for the output voltage is not the sum of both.
The maximum increase is the larger of either the
remote sense or the trim. The amount of power
delivered by the module is defined as the voltage at
the output terminals multiplied by the output current.
When using remote sense and trim: the output
voltage of the module can be increased, which at the
same output current would increase the power output
of the module. Care should be taken to ensure that
the maximum output power of the module remains at
or below the maximum rated power.

Output Voltage Programming
Trimming 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. The trim resistor should be positioned
close to the module.
If not using the trim feature, leave the TRIM pin open.
With an external resistor between the TRIM and
SENSE(-) pins (Radj-down), the output voltage set
point (Vo,adj) decreases (see Figure 36). The
following equation determines the required externalresistor value to obtain a percentage output voltage
change of ∆%.

The voltage between the Vo(+) and Vo(-) terminals
must not exceed the minimum output overvoltage
shut-down value indicated in the Feature
Specifications table. This limit includes any increase
in voltage due to remote-sense compensation and

Although the output voltage can be increased by both

The maximum increase is the larger of either the
remote sense or the trim.
The amount of power delivered by the module is
defined as the voltage at the output terminals
multiplied by the output current. When using remote
sense and trim, the output voltage of the module can
be increased, which at the same output current would
increase the power output of the module. Care should

power.

Thermal Considerations
The power modules operate in a variety of thermal
environments; however, sufficient cooling should be
provided to help ensure reliable operation.
Considerations include ambient temperature, airflow,
module power dissipation, and the need for increased
reliability. A reduction in the operating temperature of
the module will result in an increase in reliability. The
thermal data presented here is based on physical
measurements taken in a wind tunnel.
Heat-dissipating components are mounted on the
topside of the module. Heat is removed by
conduction, convection and radiation to the
surrounding environment. Proper cooling can be
verified by measuring the thermal reference
temperature (T
). The peak temperature (T
ref
occurs at the position indicated in Figures 50 - 52.
The temperature at any one of these locations should
not exceed per below table to ensure reliable
operation of the power module.

Ordering Information table.
Although the maximum T
temperature of the power
ref
modules is approximately 117 °C, you can limit this
temperature to a lower value for extremely high
reliability.
Heat Transfer via Convection
Increased airflow over the module enhances the heat
transfer via convection. Following derating figures
shows the maximum output current that can be
delivered by each module in the respective orientation
without exceeding the maximum T
versus local ambient temperature (TA) for natural
convection through 2m/s (400 ft./min).

JRW017-070 Series Power Modules DC-DC Converters
Layout Considerations
The JRW power module series are low profile in order
to be used in fine pitch system and architectures. As
such, component clearances between the bottom of
the power module and the mounting board are limited.
Either avoid placing copper areas on the outer layer
directly underneath the power module or maintain a
minimum clearance through air of 0.028 inches
between any two “opposite polarity” components,
including copper traces under the module to
components on the JRW module..
For modules with a “7” (case (heatplate) pin) and “-H”
(heatplate) option:
To meet Basic Insulation in the end product 1)
between the input and output of the module, or 2)
between the input and the earth ground, a series
capacitor (capable of withstanding 1500V dc) needs
to inserted between the case pin and the end
termination point, if the case pin is connected to the
input or the output of the JRW module or to earth
ground.
For additional layout guide-lines, refer to
FLTR100V10 data sheet.
Post Solder Cleaning and Drying
Considerations
Post solder cleaning is usually the final circuit-board
assembly process prior to electrical board testing. The
result of inadequate cleaning and drying can affect
both the reliability of a power module and the
testability of the finished circuit-board assem bly . For
guidance on appropriate soldering, cle ani ng and
drying procedures, refer to Lineage Power Board
Mounted Power Modules: Soldering and Cleaning
Application Note (AP01-056EPS).
Through-Hole Lead-Free Soldering Information
The RoHS-compliant through-hole products use the
SAC (Sn/Ag/Cu) Pb-free solder and RoHS-compliant
components. They are designed to be processed
through single or dual wave soldering machines. The
pins have an RoHS-complia nt f ini sh that is compati ble
with both Pb and Pb-free wave soldering processes.
A maximum preheat rate of 3°C/s is suggested. The
wave preheat process should be such that the
temperature of the power module board is kept below
210°C. For Pb solder, the recommended pot
36-75Vdc Input; 1.2Vdc to 12Vdc Output
temperature is 260°C, while the Pb-free solder pot is
270°C max. Not all RoHS-compliant through-hole
products can be processed with paste-through-hole
Pb or Pb-free reflow process. If additional information
is needed, please consult with your Lineage Power
