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
