Introduction

The LTC3832 is a voltage mode, high efficiency, high power step-down switching regulator controller that can operate from input voltages as low as 3V. It integrates a 0.6V reference voltage, two powerful MOSFET drivers and other features which make it possible to build cost-effective, high efficiency, high current power supplies with output voltages as low as 0.6V.

The LTC3832 uses a synchronous switching ...
