A4492 Datasheet

Triple Output Step-down Switching Regulator

Manufacturer: Allegro MicroSystems

A4492 Overview

Designed to provide the power supply requirements for a wide range of applications, the A4492 provides three high current, high performance, switching regulator outputs with independent soft start. High frequency switching allows selection of inexpensive inductors and small ceramic output capacitors. The turn-on cycles of the regulators are interleaved to minimize stresses on the input capacitors and to reduce EMI.
