AP3703 Overview
The AP3703 is a high performance AC/DC power supply controller for battery charger and adapter applications. The device uses Pulse Frequency Modulation (PFM) method to build discontinuous conduction mode (DCM) flyback power supplies. The AP3703 provides accurate constant voltage, constant current (CV/CC) regulation while removing the opto-coupler and secondary control circuitry.
