AP3783 Overview
Pin Assignments The AP3783 is a high performance AC/DC power supply controller for battery charger and adapter applications. The controller regulates the output voltage and current in the primary side by piece-wise Pulse Frequency Modulation (p-PFM) in discontinuous conduction mode (DCM). (Top View) Pin 1 Mark The AP3783 provides accurate constant voltage (CV), constant current (CC) and outstanding dynamic...
