Description
The HW/HC series power modules are isolated dc-dc converters that operate over a wide input voltage range of 18 to 36
Vdc (HC) or 36 to 75 Vdc (HW) and provide one precisely regulated output. The output is fully isolated from the input,
allowing versatile polarity configurations and grounding connections. The modules exhibit high efficiency, e.g. typical
efficiency of 87% 3.3V/5A, 86% at 2.5V/6A. Built-in filtering for both input and output minimizes the need for external
filtering. These open frame modules are available either in surface-mount (-S) or in through-hole form.
RoHS Compliant

Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings 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 being part
of complex 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 3A (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.

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 61, a 33μF electrolytic capacitor
(ESR<0.7 at 100kHz), mounted close to the power module
helps ensure the stability of the unit. Consult the factory for
further application guidelines.
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 60950-1-3, CSA C22.2 No. 60950-00, and VDE
0805:2001-12 (IEC60950-1).
If the input source is non-SELV (ELV or a hazardous voltage
greater than 60 Vdc and less than or equal to 75Vdc), for
the module’s output to be considered as meeting the
requirements for 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, including the ac mains.
One VIN pin and one VOUT pin are to be grounded, or both the
input and output pins are to be kept floating.
The input pins of the module are not operator accessible.
Another SELV reliability test is conducted on the whole system
(combination of supply source and subject module), as
required by the safety agencies, 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 appear between the
output pins and ground.
The power module has extra-low voltage (ELV) outputs
when all inputs are ELV.
For input voltages exceeding –60 Vdc but less than or equal
to –75 Vdc, these converters have been evaluated to the
applicable requirements of BASIC INSULATION between
secondary DC MAINS DISTRIBUTION input (classified as
TNV-2 in Europe) and unearthed SELV outputs.
"All flammable materials used in the manufacturing of
these modules are rated 94V-0 and UL60950 A.2 for
reduced thicknesses.
The input to these units is to be provided with a maximum
3A fast-acting fuse in the unearthed lead."
Feature Description
Remote On/Off
Two remote on/off options are available. Positive logic 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, device code suffix “1”, turns the module off during a
logic high and on during a logic low.
To maintain compatibility with LW series power modules
the Remote On/Off pin is optional for the TH (through hole)
version. Standard TH modules have no On/Off pin fitted. TH
modules ordered with device code suffix “1” are negative
logic with the On/Off pin fitted.

Figure 64. Remote On/Off Implementation.
To turn the power module on and off, the user must supply
a switch (open collector or equivalent) to control the voltage
(Von/off) between the ON/OFF terminal and the VIN(-) terminal.
Logic low is 0V Von/off 1.2V. The maximum Ion/off during a
logic low is 1mA, the switch should be maintain a logic low
level whilst sinking this current.
During a logic high, the typical Von/off generated by the
module is 5.8V, and the maximum allowable leakage
current at Von/off = 5.8V is 10μA.
If not using the remote on/off feature:
For positive logic, leave the ON/OFF pin open.
For negative logic, short the ON/OFF pin to VIN(-).
Overcurrent Protection
To provide protection in a fault (output overload) condition,
the unit is equipped with internal current-limiting circuitry
and can endure current limiting continuously. At the point
of current-limit inception, the unit enters hiccup mode. The
unit operates normally once the output current is brought
back into its specified range. The average output current
during hiccup is 10% IO, max.
Input Undervoltage Lockout
At input voltages below the input undervoltage lockout
limit, the module operation is disabled. The module will only
begin to operate once the input voltage is raised above the
undervoltage lockout turn-on threshold, VUV/ON.
Once operating, the module will continue to operate until
the input voltage is taken below the undervoltage turn-off
threshold, VUV/OFF.
Over Voltage Protection
The output overvoltage protection consists of circuitry that
internally clamps the output voltage. If a more accurate
output overvoltage protection scheme is required then this
should be implemented externally via use of the remote
on/off pin.
Over Temperature Protection
To provide protection in a fault condition, the unit is
equipped with a thermal shutdown circuit. The unit will
shutdown if the overtemperature threshold of 125 oC is
exceeded at the thermal reference point Tref . Once the unit
goes into thermal shutdown it will then wait to cool before
attempting to restart.
Output Voltage Programming
Trimming allows the output voltage set point to be
increased or decreased, this is accomplished by connecting
an external resistor between the TRIM pin and either the
VO(+) pin or the VO(-) pin (COM pin) .

should be ±0.1%.

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.
The thermal reference point, Tref used in the specifications
is shown in Figure 66. For reliable operation this
temperature should not exceed 115 oC.
Figure 66. Tref Temperature Measurement Location.
Please refer to the Application Note “Thermal
Characterization Process For Open-Frame Board-Mounted
Power Modules” for a detailed discussion of thermal
aspects including maximum device temperatures.
Heat Transfer via Convection
Increased airflow over the module enhances the heat
transfer via convection. Derating figures showing the
maximum output current that can be delivered by each
module versus local ambient temperature (TA) for natural
convection and up to 3m/s (600 ft./min) are shown in the
respective Characteristics Curves section.

For further information on designing for EMC compliance,
please refer to the FLTR100V10 data sheet (FDS01-043EPS).
Layout Considerations
The HW/HC005 power module series are low profile in order
to be used in fine pitch system card architectures. As such,
component clearance between the bottom of the power
module and the mounting 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 FLTR100V10 data
sheet.

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-compliant finish that is compatible
with both Pb and Pb-free wave soldering processes. A
maximum preheat rate of 3C/s is suggested. The wave
preheat process should be such that the temperature of
the power module board is kept below 210C. For Pb
solder, the recommended pot temperature is 260C,
while the Pb-free solder pot is 270C 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 GE representative for more details.

The ‘Z’ plane height of the pick and place location is
7.50mm nominal with an RSS tolerance of +/-0.25 mm.
Nozzle Recommendations
The module weight has been kept to a minimum by
using open frame construction. Even so, they have a
relatively large mass when compared with conventional
SMT components. Variables such as nozzle size, tip style,
vacuum pressure and placement speed should be
considered to optimize this process.
The minimum recommended nozzle diameter for reliable
operation is 6mm. The maximum nozzle outer diameter,
which will safely fit within the allowable component
spacing, is 9 mm.
Oblong or oval nozzles up to 11 x 9 mm may also be
used within the space available.

Technical Sales Representative.
Reflow Soldering Information
The HW005 family of power modules is available for
either Through-Hole (TH) or Surface Mount (SMT)
soldering. These power modules are large mass, low
thermal resistance devices and typically heat up slower
than other SMT components. It is recommended that
the customer review data sheets in order to customize
the solder reflow profile for each application board
assembly.
The following instructions must be observed when SMT
soldering these units. Failure to observe these
instructions may result in the failure of or cause damage
to the modules, and can adversely affect long-term
reliability.
The surface mountable modules in the HW005 family
use our newest SMT technology called “Column Pin” (CP)
connectors. Fig 71 shows the new CP connector before
and after reflow soldering onto the end-board assembly.

Figure 71. Column Pin Connector Before and After
Reflow Soldering.
The CP is constructed from a solid copper pin with an
integral solder ball attached, which is composed of
tin/lead (Sn/Pb) solder. The CP connector design is able
to compensate for large amounts of co-planarity and
still ensure a reliable SMT solder joint.
Typically, the eutectic solder melts at 183oC, wets the
land, and subsequently wicks the device connection.
Sufficient time must be allowed to fuse the plating on the
connection to ensure a reliable solder joint. There are
several types of SMT reflow technologies currently used
in the industry. These surface mount power modules
can be reliably soldered using natural forced convection,
IR (radiant infrared), or a combination of convection/IR.
For reliable soldering the solder reflow profile should be
established by accurately measuring the modules CP
connector temperatures.

Lead Free Soldering
The –Z version SMT modules of the HW/HC series are
lead-free (Pb-free) and RoHS compliant and are
compatible in a Pb-free soldering process. Failure to
observe the instructions below may result in the failure
of or cause damage to the modules and can adversely
affect long-term reliability.
Pb-free Reflow Profile
Power Systems will comply with J-STD-020 Rev. C
(Moisture/Reflow Sensitivity Classification for
Nonhermetic Solid State Surface Mount Devices) for both
Pb-free solder profiles and MSL classification procedures.
This standard provides a recommended forced-air-
convection reflow profile based on the volume and
thickness of the package (table 4-2). The suggested Pb-
free solder paste is Sn/Ag/Cu (SAC). The recommended
linear reflow profile using Sn/Ag/Cu solder is shown in
Figure. 74.
MSL Rating
The HW/HC series SMT modules have a MSL rating of 2A.
Storage and Handling
The recommended storage environment and handling
procedures for moisture-sensitive surface mount
packages is detailed in J-STD-033 Rev. A (Handling,
Packing, Shipping and Use of Moisture/Reflow Sensitive
Surface Mount Devices). Moisture barrier bags (MBB)
with desiccant are required for MSL ratings of 2 or
greater. These sealed packages should not be broken
until time of use. Once the original package is broken,
the floor life of the product at conditions of 30°C and
60% relative humidity varies according to the MSL rating
(see J-STD-033A). The shelf life for dry packed SMT
packages will be a minimum of 12 months from the bag
seal date, when stored at the following conditions: < 40°
C, < 90% relative humidity.
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 GE Board Mounted Power Modules: Soldering and
Cleaning Application Note (AP01-056EPS).

Solder Ball and Cleanliness Requirements
The open frame (no case or potting) power module will
meet the solder ball requirements per J-STD-001B. These
requirements state that solder balls must neither be
loose nor violate the power module minimum electrical
spacing.
The cleanliness designator of the open frame power
module is C00 (per J specification).
