Description
The JHW250-series dc-dc converters are a new generation of DC/DC power modules designed for
maximum efficiency and power density. The JHW series provide up to 250W output power in an industry
standard Half-brick, which makes it an ideal choice for high voltage and high power applications. The
converter incorporates synchronous rectification technology and innovative packaging techniques to
achieve ultra high efficiency typically 92% at 30.2V with full load. The 5-sided encapsulated case
package allows for excellent thermal performance in strict thermal environment. Threaded or nonthreaded-through holes are provided to allow easy mounting to a cold wall or addition of a heatsink for
high-temperature applications. The JHW250 series power modules are isolated dc-dc converters that
operate over a wide input voltage range of 36 to 75 Vdc and provide single precisely regulated output.
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.

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 standalone 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 fast-acting fuse with a maximum rating of 15A for JHW250 series (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
Design Considerations
Input Source Impedance
The power module should be connected to a low
ac-impedance source. Highly inductive source
impedance can affect the stability of the power module.
For the test configuration in Figure 13, a 200μF
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
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 13. Input Reflected Ripple Current Test Setup
Note: Use a 1.0 µF ceramic capacitor and a 1000µF 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.
Figure 14. Output Ripple and Noise Test Setup
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 associated E.S.R. may be dictated,
depending on the module’s control system. This series
power module requires minimum of 1000µF output
capacitance placed near output pins to ensure stable
operation in full range of load/line conditions.
The process of determining the acceptable values of
capacitance and E.S.R. is complex and is loaddependant. Tyco 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
All Versions - 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., UL60950, CSA C22.2 No. 60950-00, and
EN 60950 (VDE 0805):2001-12.
“W” Versions only - For end products connected to –48V
dc, or –60Vdc nominal DC MAINS (i.e. central office dc
battery plant), no further fault testing is required. *Note: 60V dc nominal battery plants are not available in the
U.S. or Canada.
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.
Figure 15. Output Voltage and Efficiency Test Setup
Tyco Electronics Power Systems
All Versions - 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:
ƒ
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.

Remote On/Off
ƒ
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.
“W” Versions only - 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:
ƒ
The input source is to be provided with reinforced
insulation from any hazardous voltage, including the
ac mains.
ƒ
One Vi pin and one Vo pin are to be reliably
earthed, or both the input and output pins are to be
kept floating.
ƒ
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.
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 (Von/off) and the VI (-) terminal. The
switch can be an open collector or equivalent (see
Figure 16). A logic low is Von/off = 0 V to 0.8 V. The
maximum Ion/off during a logic low is 50 µA. The switch
should maintain a logic-low voltage while sinking this 50
µA. During logic high, the maximum Von/off generated
by the power module is 5 V. The maximum allowable
leakage current of the switch at Von/off = 5V is 10 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 VIN(-).
For positive logic: leave ON/OFF pin open.
All Versions - 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 15A, (JHW250 series) fast-acting fuse in the
unearthed lead.
Feature Descriptions
Overcurrent Protection – Auto-Restart
To provide protection in a fault output overload condition,
the module is equipped with internal current-limiting
circuitry. As the load current is increased beyond its
limit, the module will start to fold back its output voltage
hence limiting output power. In the event of a severe
overload where the output voltage is pulled lower than
approximately 21V the module will enter hiccup mode to
further reduce the power dissipation of the module. The
module can survive a continuous short circuit. Once the
overload has been removed the module will auto-restart
and normal operation will resume.

Figure 16. 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 output
voltage sense range given in the Feature Specifications
table i.e.:
[Vo(+) – Vo(-)] – [SENSE(+) – SENSE(-)] ≤X% of Vo,nom.
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.
Figure 17. Effective Circuit Configuration for SingleModule Remote-Sense Operation Output Voltage
Output Voltage Set-Point Adjustment
(Trim)
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 18). The following
equation determines the required external-resistor value
to obtain a desired output voltage.
Where,
VO = Desired output voltage set point (V).
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 remotesense compensation and output voltage set-point
adjustment (trim). See Figure 17.
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 Overvoltage Protection - Latching
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 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.
Overtemperature Protection - Latching
These modules feature an overtemperature protection
circuit to safeguard against thermal damage. The circuit
shuts down and latches off the module when the
maximum baseplate reference temperature is exceeded.
The 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.
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 threshold.

Feature Descriptions (continued)
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
thermally coupled to the metal case. Heat is removed by
conduction, convection, and radiation to the surrounding
environment. Proper cooling can be verified by
measuring the case temperature. Peak temperature (TC)
occurs at the position indicated in Figure 20.
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.
For reliable operation please refer to the power derating
guidelines shown in figure 21. Under no circumstances
should the absolute maximum temperature at this point
exceed the 100°C threshold.

(Vo = 30.2V) vs Case Temperature
Layout Considerations
The JHW250 power module series are encapsulated
aluminum case packaged style, as such; component
clearance between the bottom of the power module and
the mounting (Host) board is limited. Avoid placing
copper areas on the outer layer directly underneath the
power module. Also avoid placing via interconnects
underneath the power module.
For additional layout guide-lines, refer to FLTR100V20
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 assembly. For guidance on
appropriate soldering, cleaning and drying procedures,
refer to Tyco Electronics Board Mounted Power
Modules: Soldering and Cleaning Application Note
(AP01-056EPS).
Although the maximum Tc temperature of the power
modules is 100°C, you can limit this temperature to a
lower value for extremely high reliability.
