SC2441A Datasheet 1.8v To 20v Input 2-phase Synchronous Step-down Controllers

Manufacturer: SEMTECH

Overview: 1.8V to 20V Input 2-Phase Synchronous www.DataSheet4U.com Step-down Controllers with Step-up Converter POWER.

General Description

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 below 4.5V.
