Diodes Inc. AP3783/R Power Supply Controllers are 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). They provides accurate constant voltage (CV), constant current (CC) and outstanding dynamic performance without requiring an opto-coupler.
