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.

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

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.

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, CSA C22.2 No.

Remote Sense
Input Under Voltage Lockout
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.
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 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.
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,

various types of output voltage sequencing in their
applications. This is accomplished via an additional
sequencing pin. When not using the sequencing

tied to VIN.

Open
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

connecting a resistor, Rmargin-down, from the Trim pin
to output pin for margining-down. Figure 53 shows

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

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 converters to shut
down and restart together.
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

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).
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

In a conventional Tin/Lead (Sn/Pb) solder process
Surface Mount Information
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.
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.

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.

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 2.
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
