Description
Austin SuperLynxTM II SIP power modules are non-isolated dc-dc converters that can deliver up to 16A of output current
with full load efficiency of 95% at 3.3V output. These modules provide a precisely regulated output voltage programmable
via external resistor from 0.75Vdc to 3.3Vdc over a wide range of input voltage (VIN = 2.4 – 5.5Vdc). Austin SuperLynxTM II
has a sequencing feature, EZ-SEQUENCETM that enable designers to implement various types of output voltage
sequencing when powering multiple modules on board. Their open-frame construction and small footprint enable
designers to develop cost- and space-efficient solutions. In addition to sequencing, standard features include remote
On/Off, remote sense, programmable output voltage, over current and over temperature 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
The Austin SuperLynxTM 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.
To minimize input voltage ripple, low-ESR polymer and ceramic
capacitors are recommended at the input of the module.
Figure 26 shows the 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

Design Considerations (continued)
Output Filtering
The Austin SuperLynxTM II 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.

Feature Description
Remote On/Off
Austin SuperLynxTM II SIP power modules feature an On/Off pin
for remote On/Off operation. Two On/Off logic options are
available in the Austin SuperLynxTM II series modules. Positive
Logic On/Off signal, device code suffix “4”, turns the module ON
during a logic High on the On/Off pin and turns the module OFF
during a logic Low. Negative logic On/Off signal, no device
code suffix, turns the module OFF during logic High and turns
the module ON during logic Low.
For positive logic modules, the circuit configuration for using
the On/Off pin is shown in Figure 28. The On/Off pin is an open
collector/drain logic input signal (Von/Off) that is referenced to
ground. During a logic-high (On/Off pin is pulled high internal
to the module) when the transistor Q1 is in the Off state, the
power module is ON. Maximum allowable leakage current of
the transistor when Von/off = VIN,max is 10µA. Applying a logic-
low when the transistor Q1 is turned-On, the power module is
OFF. During this state VOn/Off must be less than 0.3V. When
not using positive logic On/off pin, leave the pin unconnected
or tie to VIN.

For negative logic On/Off devices, the circuit configuration is
shown is Figure 29. The On/Off pin is pulled high with an
external pull-up resistor (typical Rpull-up = 68k, +/- 5%). 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 over temperature protection in a fault condition, the
unit relies upon the thermal protection feature of the controller
IC. 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 restart after it
cools down.

Feature Descriptions (continued)
Output Voltage Programming
The output voltage of the Austin SuperLynxTM II SIP can be
programmed to any voltage from 0.75 Vdc to 3.3 Vdc by
connecting a single resistor (shown as Rtrim in Figure 30)
between the TRIM and GND pins of the module. Without an
external resistor between 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 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 II 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.

Feature Descriptions (continued)
Voltage Sequencing
Austin SuperLynxTM II series of modules include a sequencing
feature, EZ-SEQUENCE that enables users to implement various
types of output voltage sequencing in their applications. This is
accomplished via an additional sequencing pin. When not
using the sequencing feature, either tie the SEQ pin to VIN or
leave it unconnected.
When an analog voltage is applied to the SEQ pin, the output
voltage tracks this voltage until the output reaches the set-
point voltage. The SEQ voltage must be set higher than the
set-point voltage of the module. The output voltage follows the
voltage on the SEQ pin on a one-to-one volt basis. By
connecting multiple modules together, customers can get
multiple modules to track their output voltages to the voltage
applied on the SEQ pin.
For proper voltage sequencing, first, input voltage is applied to
the module. The On/Off pin of the module is left unconnected
(or tied to GND for negative logic modules or tied to VIN for
positive logic modules) so that the module is ON by default.
After applying input voltage to the module, a minimum of
10msec delay is required before applying voltage on the SEQ
pin. During this time, potential of 50mV (± 10 mV) is maintained
on the SEQ pin. After 10msec delay, an analog voltage is
applied to the SEQ pin and the output voltage of the module
will track this voltage on a one-to-one volt bases until output
reaches the set-point voltage. To initiate simultaneous
shutdown of the modules, the SEQ pin voltage is lowered in a
controlled manner. Output voltage of the modules tracks the
voltages below their set-point voltages on a one-to-one basis.
A valid input voltage must be maintained until the tracking and
output voltages reach ground potential.
When using the EZ-SEQUENCETM feature to control start-up of
the module, pre-bias immunity feature during start-up is
disabled. The pre-bias immunity feature of the module relies
on the module being in the diode-mode during start-up. When
using the EZ-SEQUENCETM feature, modules goes through an
internal set-up time of 10msec, and will be in synchronous
rectification mode when voltage at the SEQ pin is applied. This
will result in sinking current in the module if pre-bias voltage is
present at the output of the module. When pre-bias immunity
during start-up is required, the EZ-SEQUENCETM feature must
be disabled. For additional guidelines on using EZ-
SEQUENCETM feature of Austin SuperLynxTM II, contact the GE
technical representative for preliminary application note on
output voltage sequencing using Austin Lynx II series.
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.

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 34. Note that the
airflow is parallel to the long axis of the module as shown in
figure 33. The derating data applies to airflow in either
direction of the module’s long axis.
Figure 33. Tref Temperature measurement location.
The thermal reference point, Tref used in the specifications is
shown in Figure 33. 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 34. 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 temperatures (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.
