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. Highly inductive source impedance can
affect the stability of the power module. For the test
configuration in Figure 43, 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 (IEC60950, 3rd Edition).
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.
The input to these units is to be provided with a maximum 3A
time-delay fuse in the ungrounded 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. The On/Off pin shall always be fitted on SMT
versions.

Figure 46. Circuit configuration for using 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 50μA.
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.
Output Voltage Programming
Trimming allows the user to increase or decrease the output
voltage set point of the module. This is accomplished by
connecting an external resistor between the TRIM pin and
either the Vout+ pin or the Vout- pin.
Note: Trim pin is optional on TH module version and always
present on SMT versions.
Trim Down – Decrease Output Voltage
By connecting an external resistor between the TRIM pin and
Vout+ pin (Radj-down), the output voltage set point decreases
(see figure 17). The following equation determines the external
resistor value to obtain an output voltage change from Vo,

The combination of the output voltage adjustment and the
output voltage initial tolerance must not exceed the allowable
trim range of 90% to 110% of the nominal output voltage as
measured between the Vout+ and Vout- pins.
The SW/SC power modules have a fixed current-limit set point.
Therefore, as the output voltage is adjusted down, the available
output power is reduced.

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 49. For reliable operation this temperature
should not exceed 120oC.
Tref
Figure 49. Tref Temperature Measurement Location.
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.
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.
EMC Considerations
Figure 50 shows a suggested configuration to meet the
conducted emission limits of EN55022 Class B.
Notes: C1, C2, C3 and C6 are low impedance SMT ceramics. C4
is a low impedance polymer film type (Paktron CS4). Common

For further information on designing for EMC compliance,
please refer to the FLTR100V10 data sheet (FDS01-043EPS).
Layout Considerations
The SW/SC 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 the FLTR100V10 data
sheet.
The SW/SC family of power modules is available for either
Through-Hole (TH) or Surface Mount (SMT) soldering.
Through-Hole Soldering Information
The RoHS-compliant (Z codes) 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 GEPower
representative for more details.
Surface Mount Information
Pick and Place
The SW/SC-SR series of DC-to-DC power converters use an
open-frame construction and are designed for surface mount
assembly within a fully automated manufacturing process.
The SW/SC-SR series modules are designed to use the main
magnetic component surface to allow for pick and place.

Note: All dimensions in mm.
Figure 52. Pick and Place Location.
Z Plane Height
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 5mm. The maximum nozzle outer diameter, which
will safely fit within the allowable component spacing, is
6.5mm.
Oblong or oval nozzles up to 11 x 6 mm may also be used
within the space available.

Reflow Soldering Information
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.
Surface Mount Information (continued)
The surface mountable modules in the SW/SC family use our
SMT technology called “Column Pin” (CP) connectors. Figure
53 shows the CP connector before and after reflow soldering
onto the end-board assembly.
Power Module Board
Insulator
Solder Ball
End assembly PCB
Figure 53. 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 (Sn63/Pb37)
solder for non-Z codes, or Sn/Ag3.8/Cu0.7 (SAC) solder for –Z
codes. 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 (Sn/Pb
solder) or 217-218 oC (SAC solder), 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. The
recommended linear reflow profile using Sn/Pb solder is shown
in Figure 54 and 55. For reliable soldering the solder reflow
profile should be established by accurately measuring the
modules CP connector temperatures.

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. 56.

MSL Rating
The SW/SC 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 Lineage Power Board
Mounted Power Modules: Soldering and Cleaning Application
Note (AN04-001).

* Please contact GE Sales Representative for availability of these options, samples, minimum order quantity and lead times. Legacy
device codes may contain a –B option suffix to indicate 100% factory Hi-Pot tested to the isolation voltage specified in the
Absolute Maximum Ratings table. The 100% Hi-Pot test is now applied to all device codes, with or without the –B option suffix.
Existing comcodes for devices with the –B suffix are still valid; however, no new comcodes for devices containing the –B suffix will
be created.
** When adding multiple options to the product code, add numerical suffix codes in the descending order.
† Either negative or positive logic (1 or 4), and output voltage adjustment (trim, 9) must be ordered on surface mount , SMT (-SR)
device codes. Both the on/off pin and trim pin will be provided on all –SR device codes.
