SC2441A Datasheet (Semtech Corporation) - 1.8V to 20V Input 2-Phase Synchronous Step-down Controllers

SC2441A, 1.8V to 20V Input 2-Phase Synchronous Step-down Controllers

The SC2441A is a programmable frequency dual independent or dual/multiple phase single output peak current-mode step-down switching regulator controller.

It is capable of operating from 1.8V to 20V input.

A 0.6A step-up converter in the SC2441A generates an auxiliary gate drive supply when VIN is be
