Description
The Austin MegaLynx series SMT power modules are non-isolated DC-DC converters in an industry standard package that can deliver
up to 30A of output current with a full load efficiency of 92% at 2.5Vdc output voltage (VIN = 12Vdc). The ATH series of modules
operate off an input voltage from 4.5 to 5.5Vdc and provide an output voltage that is programmable from 0.8 to 3.63Vdc, while the
ATS series of modules have an input voltage range from 6 to 14V and provide a programmable output voltage ranging from 0.8 to
3.63Vdc. Both series have a sequencing feature that enables designers to implement various types of output voltage sequencing
when powering multiple modules on the board. Additional features include remote On/Off, adjustable output voltage, remote sense,
over current, over temperature protection and active current sharing between modules.

Design Considerations
The Austin MegaLynxTM module should be connected to a low-
impedance source. A highly inductive source can affect the
stability of the module. An input capacitor 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 ceramic capacitors
are recommended at the input of the module. Figure 46
shows the input ripple voltage for various output voltages at
30A of load current with 1x22 µF or 2x22 µF ceramic
capacitors and an input of 12V. Figure 47 shows data for the
5Vin case, with 2x22µF and 2x47µF of ceramic capacitors at
the input, and for a load current of 30A.

Output Filtering
The Austin MegaLynxTM modules are designed for low output
ripple voltage and will meet the maximum output ripple
specification with 0.1 µF ceramic and 10 µF ceramic 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. Figure 48 shows the output ripple voltage for various
output voltages at 30A of load current with different external
capacitance values and an input of 12V. Figure 49 shows data
for the 5Vin case for various output voltages at 30A of load
current with different external capacitance values. For stable
operation of the module, limit the capacitance to less than the
maximum output capacitance as specified in the electrical
specification table.

with external 1x10 µF, 1x47 µF, 2x47 µF or 4x47 µF ceramic
capacitors at the output (30A load). Input voltage is 12V.

with external 1x10 µF, 1x47 µF, 2x47 µF or 4x47 µF ceramic
capacitors at the output (30A load). Input voltage is 5V.
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
ANSI/UL 62368-1 and CAN/CSA C22.2 No. 62368-1
Recognized, DIN VDE 0868-1/A11:2017 (EN62368-
1:2014/A11:2017)
For the converter output to be considered meeting the
requirements of safety extra-low voltage (SELV) or ES1, the
input must meet SELV/ES1 requirements. The power module
has extra-low voltage (ELV) outputs when all inputs are ELV.
Feature Descriptions
Remote On/Off
The Austin MegaLynxTM SMT power modules feature a On/Off
pin for remote On/Off operation. If not using the On/Off pin,
connect the pin to ground (the module will be ON). The
On/Off signal (Von/off) is referenced to ground. Circuit
configuration for remote On/Off operation of the module
using the On/Off pin is shown in Figure 50.
During a Logic High on the On/Off pin (transistor Q1 is OFF),
the module remains OFF. The external resistor R1 should be
chosen to maintain 3.0V minimum on the On/Off pin to
ensure that the module is OFF when transistor Q1 is in the
OFF state. Suitable values for R1 are 4.7K for input voltage of
12V and 3K for 5Vin. During Logic-Low when Q1 is turned ON,
the module is turned ON. The ATS030A0X3-62SRHZ and
ATS030A0X3-62SRPHZ modules have a higher value resistor of
100K connected internally between the gate and source of the
internal FET used to control the PWM Enable line.
The On/Off pin can also be used to synchronize the output
voltage start-up and shutdown of multiple modules in parallel.
By connecting On/Off pins of multiple modules, the output
start-up can be synchronized (please refer to characterization
curves). When On/Off pins are connected together, all
modules will shutdown if any one of the modules gets
disabled due to undervoltage lockout or over temperature
protection.

Remote Sense
The Austin MegaLynxTM SMT 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
51). 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 of the module.

Over Current 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.
Over Temperature Protection
To provide protection in a fault condition, the unit is equipped
with a thermal shutdown circuit. The unit will shutdown if the
overtemperature threshold of 125oC is exceeded at the
thermal reference point Tref. The thermal shutdown is not
intended as a guarantee that the unit will survive
temperatures beyond its rating. Once the unit goes into
thermal shutdown it will then wait to cool before attempting
to restart.
Input Under Voltage Lockout
At input voltages below the input undervoltage lockout limit,
the module operation is disabled. The module will begin to
operate at an input voltage above the undervoltage lockout
turn-on threshold.
Output Voltage Programming
The output voltage of the Austin MegaLynxTM can be
programmed to any voltage from 0.8dc to 3.63Vdc by
connecting a resistor (shown as Rtrim in Figure 52) between
Trim and GND pins of the module. Without an external
resistor between Trim and GND pins, the output of the
module will be 0.8Vdc. To calculate the value of the trim
resistor, Rtrim for a desired output voltage, use the following
equation:

By using a ±0.5% tolerance trim resistor with a TC of

specified in the electrical specification. Table 1 provides Rtrim
values required for some common output voltages. The POL
Programming Tool, available at www.gecriticalpower.com

Voltage Margining
Output voltage margining can be implemented in the Austin
MegaLynxTM 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 output pin for margining-down. Figure 53 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.

Voltage Sequencing
The Austin MegaLynxTM series of modules include a
sequencing feature 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 leave the SEQ pin
unconnected or tied to VIN.
For proper voltage sequencing, first, input voltage is applied
to the module. The On/Off pin of the module is or tied to
GND so that the module is ON by default. After applying input
voltage to the module, a delay of 10msec minimum is required
before applying voltage on the SEQ pin. During this delay
time, the SEQ pin should be kept at a voltage of 50mV (± 20
mV). After the 10msec delay, the voltage applied to the SEQ
pin is allowed to vary and the output voltage of the module
will track this voltage on a one-to-one volt basis until the
output reaches the set-point voltage. To initiate simultaneous
shutdown of the modules, the SEQ pin voltage is lowered in a
controlled manner. The output voltages of the modules track
the sequence pin voltage when it falls below their set-point
voltages. A valid input voltage must be maintained until the
tracking and output voltages reach zero to ensure a controlled
shutdown of the modules. For a more detailed description of
sequencing, please refer to Application Note AN04-008 titled
“Guidelines for Sequencing of Multiple Modules”.
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.
Active Load Sharing (-P Option)
For additional power requirements, the Austin MegaLynx
series power module is also available with a parallel option.
Up to five modules can be configured, in parallel, with active
load sharing. Good layout techniques should be observed
when using multiple units in parallel. To implement forced
load sharing, the following connections should be made:
• The share pins of all units in parallel must be connected
together. The path of these connections should be as
direct as possible.
• All remote-sense pins should be connected to the power
bus at the same point, i.e., connect all the SENSE(+) pins
to the (+) side of the bus. Close proximity and directness
are necessary for good noise immunity
Some special considerations apply for design of converters in
parallel operation:
• When sizing the number of modules required for parallel
operation, take note of the fact that current sharing has
some tolerance. In addition, under transient condtions
such as a dynamic load change and during startup, all
converter output currents will not be equal. To allow for
such variation and avoid the likelihood of a converter
shutting off due to a current overload, the total capacity

of the paralleled system should be no more than 75% of
the sum of the individual converters. As an example, for a
system of four ATS030A0X3-SR converters the parallel,
the total current drawn should be less that 75% of (4 x
30A) , i.e. less than 90A.
• All modules should be turned on and off together. This is
so that all modules come up at the same time avoiding
the problem of one converter sourcing current into the
other leading to an overcurrent trip condition. To ensure
that all modules come up simultaneously, the on/off pins
of all paralleled converters should be tied together and
the converters enabled and disabled using the on/off pin.
• The share bus is not designed for redundant operation
and the system will be non-functional upon failure of one
of the unit when multiple units are in parallel. In
particular, if one of the converters shuts down during
operation, the other converters may also shut down due
to their outputs hitting current limit. In such a situation,
unless a coordinated restart is ensured, the system may
never properly restart since different converters will try
to restart at different times causing an overload
condition and subsequent shutdown. This situation can
be avoided by having an external output voltage monitor
circuit that detects a shutdown condition and forces all

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 54. Note that the
airflow is parallel to the short axis of the module as shown in
Figure 55. The derating data applies to airflow in either
direction of the module’s long axis.
Figure 54. Thermal Test Setup.
The thermal reference points, Tref used in the specifications are
shown in Figure 56. For reliable operation the temperatures at
these points should not exceed 125oC. 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.

Surface Mount Information
Pick and Place
The Austin MegaLynxTM SMT modules use an open frame
construction and are designed for a fully automated assembly
process. The modules are fitted with a label designed to
provide a large surface area for pick and place operations.
The label meets all the requirements for surface mount
processing, as well as safety standards, and is able to
withstand reflow temperatures of up to 300oC. The label also
carries product information such as product code, serial
number and location of manufacture.
Figure 57. Pick and Place Location.
Nozzle Recommendations
The module weight has been kept to a minimum by using
open frame construction. Even so, these modules have a
relatively large mass when compared to conventional SMT
components. Variables such as nozzle size, tip style, vacuum
pressure and pick & placement speed should be considered to
optimize this process. The minimum recommended inside
nozzle diameter for reliable operation is 3mm. The maximum
nozzle outer diameter, which will safely fit within the
allowable component spacing, is 5 mm max.
Tin Lead Soldering
The Austin MegaLynxTM SMT power modules are lead free
modules and can be soldered either in a lead-free solder
process or in a conventional Tin/Lead (Sn/Pb) process. 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 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.
In a conventional Tin/Lead (Sn/Pb) solder process peak reflow
temperatures are limited to less than 235oC. 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.

Surface Mount Information (continued)
Lead Free Soldering
The –Z version MegaLynx SMT modules are lead-free (Pb-free)
and RoHS compliant and are both forward and backward
compatible in a Pb-free and a SnPb 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.
Pb-free Reflow Profile
Power Systems will comply with J-STD-020 Rev. C
(Moisture/Reflow Sensitivity Classification for Nonhermetic
Solid State Surface Mount Devices) for both Pb-free solder
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. 60.
MSL Rating
The Austin MegaLynxTM 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 Board Mounted Power Modules:
Soldering and Cleaning Application Note (AN04-001).
