Triple 10A Step-Down

DC/DC µModule Regulator

FeaTures

DescripTion

The LTM^®4633 µModule^®(micromodule) regulator com-

bines three complete 10A switching mode DC/DC con-

verters into one small package. Included in the package

are the switching controllers, power FETs, inductors, and

most support components. The LTM4633’s three regula-

tors operate from 4.7V to 16V input rail(s) or 2.375V to
