RT5771A Datasheet Synchronous Step-Down Converter

Manufacturer: Richtek

Overview: ® RT5771A 3A, 1MHz, Synchronous Step-Down Converter General.

General Description

The RT5771A is a high efficiency synchronous, step-down DC-DC converter.

Its input voltage ranges from 2.7V to 5.5V that provides an adjustable regulated output voltage from 0.6V to VIN while delivering up to 3A of output current.

The internal synchronous low on-resistance power switches increase efficiency and eliminate the need for an external Schottky diode.
