AP3785T Overview
The AP3785T is a high performance AC/DC power supply controller for battery charger and adapter applications. It can meet less than 10mW standby power for “Super Star” charger criteria. The device uses Pulse Frequency Modulation (PFM) method to build discontinuous conduction mode (DCM) flyback power supplies.
