Beschreibung

The RT5759 is a high efficiency synchronous step-down DC-DC converter. Its input voltage range is from 3V to 6V and provides an VID Control regulated output voltage from 0.6V to 1.5V step 10mV while delivering up to 9A of output current. This document explains the function and use of the RT5759 evaluation board (EVB), and provides information to enable operation, modification of the evaluation board and circuit to meet individual requirements.
