SC4602B Datasheet Step Down Controller

Manufacturer: SEMTECH

Overview: High Efficiency Synchronous, Step Down Controller POWER MANAGEMENT.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The SC4602A/B is a voltage mode step down (buck) regulator controller that provides accurate high efficiency power conversion from an input supply range of 2.75V to 5.5V.

A high level of integration reduces external ponent count and makes it suitable for low voltage applications where cost, size and efficiency are critical.

The SC4602A/B drives external plementary power MOSFETs;
