Description
Austin SuperLynxTM 12V SIP power modules are non-isolated dc-dc converters that can deliver up to 16A of output current
with full load efficiency of 92% at 3.3V output. These modules provide a precisely regulated output voltage ranging from
0.75Vdc to 5.5Vdc, programmable via an external resistor over a wide range of input voltage (VIN = 10 – 14Vdc). Their
open-frame construction and small footprint enable designers to develop cost- and space-efficient solutions. Standard
features include remote On/Off, remote sense, output voltage adjustment, overcurrent and overtemperature protection.

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 a
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 15 A
(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 Filtering
The Austin SuperLynxTM 12V SIP module should be connected
to a low-impedance source. A highly inductive source can
affect the stability of the module. An input capacitance must
be placed directly adjacent to the input pin of the module, to
minimize input ripple voltage and ensure module stability.
In a typical application, 6x47 µF low-ESR tantalum capacitors
(AVX part #: TPSE476M025R0100, 47µF 25V 100 mΩ ESR
tantalum capacitor) will be sufficient to provide adequate ripple
voltage at the input of the module. To further minimize ripple
voltage at the input, very low ESR ceramic capacitors are
recommended at the input of the module. Figure 26 shows
input ripple voltage (mVp-p) for various outputs with 6x47 µF
tantalum capacitors and with 6x22 µF ceramic capacitor (TDK
part #: C4532X5R1C226M) at full load. .

Design Considerations (continued)
Output Filtering
The Austin SuperLynxTM 12V SIP module is designed for low
output ripple voltage and will meet the maximum output ripple
specification with 1 µF ceramic and 10 µF tantalum capacitors
at the output of the module. However, additional output
filtering may be required by the system designer for a number
of reasons. First, there may be a need to further reduce the
output ripple and noise of the module. Second, the dynamic
response characteristics may need to be customized to a
particular load step change.
To reduce the output ripple and improve the dynamic response
to a step load change, additional capacitance at the output
can be used. Low ESR polymer and ceramic capacitors are
recommended to improve the dynamic response of the
module. For stable operation of the module, limit the
capacitance to less than the maximum output capacitance as
specified in the electrical specification table.
Safety Considerations
For safety agency approval the power module must be
installed in compliance with the spacing and separation
requirements of the end-use safety agency standards, i.e., UL
60950-1, CSA C22.2 No. 60950-1-03, and VDE 0850:2001-12
(EN60950-1) Licensed.
For the converter output to be considered meeting the
requirements of safety extra-low voltage (SELV), the input must
meet SELV requirements. The power module has extra-low
voltage (ELV) outputs when all inputs are ELV.
The input to these units is to be provided with a fast-acting
fuse with a maximum rating of 6A in the positive input lead.

Feature Description
Remote On/Off
The Austin SuperLynxTM 12V SIP power modules feature an
On/Off pin for remote On/Off operation of the module. If not
using the remote On/Off pin, leave the pin open (module will be
On). The On/Off pin signal (Von/Off) is referenced to ground. To
switch the module on and off using remote On/Off, connect an
open collector npn transistor or N-channel FET between the
On/Off pin and the ground pin (See Figure 27).
During a logic-high (On/Off pin is pulled high internal to the
module) when the transistor is in the Off state, the power

transistor when Von/off = VIN,max is 10µA. During a logic-low
when the transistor is turned-on, the power module is OFF.
During this state VOn/Off is less than 0.3V and the maximum
IOn/Off = 1mA.

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 typical average output current during
hiccup is 3A.
Input Undervoltage Lockout
At input voltages below the input undervoltage lockout limit,
module operation is disabled. The module will begin to operate
at an input voltage above the undervoltage lockout turn-on
threshold.
Overtemperature Protection
To provide protection in a fault condition, the unit is
equipped with a thermal shutdown circuit. The unit will
shutdown if the thermal reference point Tref, exceeds 125oC
(typical), but the thermal shutdown is not intended as a
guarantee that the unit will survive temperatures beyond its
rating. The module will automatically restarts after it cools
down.
Output Voltage Programming
The output voltage of the Austin SuperLynxTM 12V can be
programmed to any voltage from 0.75Vdc to 5.5Vdc by
connecting a resistor (shown as Rtrim in Figure 28) between
the Trim and GND pins of the module. Without an external
resistor between the Trim and GND pins, the output of the
module will be 0.7525Vdc. To calculate the value of the trim
resistor, Rtrim for a desired output voltage, use the following
equation:

By using a 1% tolerance trim resistor, set point tolerance of
±2% is achieved as specified in the electrical specification. The
POL Programming Tool, available at www.gecriticalpower.com
under the Design Tools section, helps determine the required
external trim resistor needed for a specific output voltage.
The amount of power delivered by the module is defined as the
voltage at the output terminals multiplied by the output
current. When using the trim feature, 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 (Pmax =
Vo,set x Io,max).
Voltage Margining
Output voltage margining can be implemented in the Austin
SuperLynxTM 12V SIP modules by connecting a resistor, Rmargin-
up, from the Trim pin to the ground pin for margining-up the
output voltage and by connecting a resistor, Rmargin-down, from
the Trim pin to the Output pin for margining-down. Figure 30
shows the circuit configuration for output voltage margining.
The Lynx Programming Tool, available at
www.gecriticalpower.com under the Design Tools section, also
calculates the values of Rmargin-up and Rmargin-down for a specific
output voltage and % margin. Please consult your local GE
technical representative for additional details.

Remote Sense
The Austin SuperLynxTM 12V SIP power modules have a Remote
Sense feature to minimize the effects of distribution losses by
regulating the voltage at the Remote Sense pin (See Figure 31).
The voltage between the Sense pin and Vo pin must not exceed
0.5V.
The amount of power delivered by the module is defined as the
output voltage multiplied by the output current (Vo x Io). When
using Remote Sense, the output voltage of the module can
increase, which if the same output is maintained, increases the
power output by the module. Make sure that the maximum
output power of the module remains at or below the maximum
rated power. When the Remote Sense feature is not being
used, connect the Remote Sense pin to output pin.

Thermal Considerations
Power modules operate in a variety of thermal environments;
however, sufficient cooling should always 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 test set-up is shown in Figure 33. Note that the
airflow is parallel to the long axis of the module as shown in
figure 32. The derating data applies to airflow in either
direction of the module’s long axis.
Figure 32. Tref Temperature measurement location.
The thermal reference point, Tref used in the specifications is
shown in Figure 32. For reliable operation this temperature
should not exceed 115oC.
The output power of the module should not exceed the rated
power of the module (Vo,set x Io,max).
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.
Figure 33. Thermal Test Set-up.
Heat Transfer via Convection
Increased airflow over the module enhances the heat
transfer via convection. Thermal derating curves showing
the maximum output current that can be delivered at
different local ambient temperature (TA) for airflow
conditions ranging from natural convection and up to 2m/s
(400 ft./min) are shown in the Characteristics Curves section.

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 Board Mounted Power
Modules: Soldering and Cleaning Application Note.
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 GE technical representative for more details.
