Data Sheet
June 3, 2009
Austin MegaLynx
TM
: Non-Isolated DC-DC Power Modules:
4.5 – 5.5Vdc input; 0.8 – 3.63Vdc output; 30A output current
6.0 – 14Vdc input; 0.8 – 5.5Vdc output; 25A output current
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.
