Description
The Austin MegaLynx series SIP 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 3.3Vdc 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 5.5Vdc. 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.

Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are absolute stress ratings
only, functional operation of the device is not implied at these or any other conditions in excess of those given in the operations
sections of the data sheet. Exposure to absolute maximum ratings for extended periods can adversely affect the device reliability.
