SC4601 Datasheet Step Down Controller

Manufacturer: SEMTECH

Overview: Low Input, High Efficiency Synchronous, Step Down Controller POWER.

General Description

The SC4601 is a voltage mode step down (buck) regulator controller that provides accurate high efficiency power conversion from input supply range 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.
