LTM4648
Low VIN, 10A Step-Down
ВµModule Regulator
Features Description n n n The LTM В® 4648 is a 10A low V IN step-down
DC/DC ВµModuleВ® (micromodule) regulator. Included in
the package are the switching controller, power FETs,
inductor and all support components. Operating over
an input voltage range of 2.375V to 5.5V, the LTM4648
supports an output voltage range of 0.6V to 5V, set by a
single external resistor. This high efficiency design delivers
up to 10A continuous current. Only bulk input and output
capacitors are needed. 10A DC Output Current
