General Description

The RT8055 is a high efficiency synchronous, step-down DC/DC converter.

Its input voltage range is from 2.6V to 5.5V and provides an adjustable regulated output voltage from 0.8V to 5V 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.

Key Features
