Overview

1.
8V to 20V Input 2-Phase Synchronous com Step-down Controllers with Step-up Converter POWER MANAGEMENT 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.
This makes the SC2441A well suited for applications where a low-voltage input (<3.
3V) is to be stepped down for lower voltage logic, yet the input is too low to drive power MOSFETs efficiently.
The SC2441A employs a phase-locked synchronizing circuit that al...
