The IP is a high efficiency, low ripple, current mode buck switching regulator. The internal synchronous switches increase the efficiency and eliminate the need for external Schottky diode.
The input voltage range is from 2.7 to 3.6V, the max output current is 360mA, and the current limit is about 800mA.
