Description
The SW/SC series power modules are isolated dc-dc converters that operate over a wide range of input voltage (VIN
= 18 - 36Vdc for SC modules and VIN = 36 – 75Vdc for SW modules) and provide a single precisely regulated
output. This series is a low cost, smaller size alternative to the existing LW/LAW/LC with enhanced performance
parameters. The output is fully isolated from the input, allowing versatile polarity configurations and grounding
connections. The modules exhibit high efficiency, typical efficiency of 86% for 5.0V/3A. Built-in filtering for both
input and output minimizes the need for external filtering.
RoHS Compliant

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<0.7Ω 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 (-B option only).

18-36Vdc & 36-75Vdc Input; 3.3-15Vdc Output; 1-3.5A Output Current
Tyco Electronics Power Systems 14
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.

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.
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

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

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.
EMC Considerations

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.

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 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
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 Tyco Electronics
Power System representative for more details.
Surface Mount Information
Packaging Details
The surface mount versions of the SW/SC family
(suffix –SR) are supplied as standard in tape and reel.
Full details of this packaging will be provided in the
full revision of this data sheet.
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.
For further information please contact your local Tyco
Electronics Power Systems Technical Sales
Representative.
Reflow Soldering Information
The SW/SC 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 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.

Tyco Electronics Power Systems 22
Surface Mount Information (continued)
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 SW/SC 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.

MSL Rating

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 Tyco Electronics Board
