Description
Austin SuperLynxTM SIP (Single In-line package) power modules are non-isolated dc-dc converters that can deliver up to
16A of output current with full load efficiency of 95.0% at 3.3V output. These modules provide a precisely regulated
output voltage programmable via external resistor from 0.75Vdc to 3.63Vdc over a wide range of input voltage (VIN = 3.0 –
5.5Vdc). The open-frame construction and small footprint enable designers to develop cost- and space-efficient solutions.
Standard features include remote On/Off, remote sense, programmable output voltage, 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 20A, fast-acting, glass type fuse rated for 32V
(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
Austin SuperLynxTM SIP module should be connected to a
low ac-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.
To minimize input voltage ripple, low-ESR polymer and ceramic
capacitors are recommended at the input of the module.
Figure 26 shows input ripple voltage (mVp-p) for various
outputs with 1x150 µF polymer capacitors (Panasonic p/n:
EEFUE0J151R, Sanyo p/n: 6TPE150M) in parallel with 1 x 47 µF
ceramic capacitor (Panasonic p/n: ECJ-5YB0J476M, Taiyo-
Yuden p/n: CEJMK432BJ476MMT) at full load. Figure 27 shows
the input ripple with 2x150 µF polymer capacitors in parallel
with 2 x 47 µF ceramic capacitor at full load.

Design Considerations (continued)
Output Filtering
The Austin SuperLynxTM 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 20A in the positive input lead.

The Austin SuperLynxTM SIP power modules feature an On/Off
pin for remote On/Off operation. The On/Off pin is pulled high
with an external pull-up resistor (typical Rpull-up = 68k, ± 5%)
as shown in Fig. 28. When transistor Q1 is in the Off state, logic
High is applied to the On/Off pin and the power module is Off.
The minimum On/off voltage for logic High on the On/Off pin is
1.5Vdc. To turn the module ON, logic Low is applied to the
On/Off pin by turning ON Q1. When not using the negative logic
On/Off, leave the pin unconnected or tie to GND.

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 3.5A.
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 SIP can be
programmed to any voltage from 0.75 Vdc to 3.63 Vdc by
connecting a single resistor (shown as Rtrim in Figure 29)
between the TRIM and GND pins of the module. Without an
external resistor between the TRIM pin and the ground, the
output voltage of the module is 0.7525 Vdc. To calculate the
value of the resistor Rtrim for a particular output voltage Vo,
use the following equation:

By a using 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.
Voltage Margining
Output voltage margining can be implemented in the Austin
SuperLynxTM 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 31 shows
the circuit configuration for output voltage margining. The POL
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 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 32).
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 the output pin of the
module.

Thermal Considerations
The 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 Fig. 33. Note that the
airflow is parallel to the long axis of the module as shown in
Fig. 34. The derating data applies to airflow in either direction
of the module’s long axis.
Figure 33. Thermal Test Set-up.
The thermal reference point, Tref used in the specifications is
shown in Figure 33. For reliable operation this temperature
should not exceed 115 oC. 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.
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.
Figure 34. Tref Temperature measurement location
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.
