RT5771D Overview
The RT5771D 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.
