TheLTM®4630isadual18Aorsingle36Aoutputswitching  
modestep-downDC/DCµModule® (micromodule)regula-  
tor. Included in the package are the switching controllers,  
power FETs, inductors, and all supporting components.  
Operating from an input voltage range of 4.5V to 15V, the  
LTM4630supportstwooutputseachwithanoutputvoltage  
range of 0.6V to 1.8V, each set by a single external resistor.  
Its high efficiency design delivers up to 18A continuous  
current for each output. Only a few input and output ca-  
pacitors are needed. The LTM4630 is pin compatible with  
the LTM4620 and LTM4620A (dual 13A, single 26A) and  
the LTM4628 (dual 8A, single 16A).
