AP3983R Overview
Pin Assignments The AP3983R is a power switcher for power supplies with better conversion efficiency, better voltage & current accuracy, and improved protection functions. Typical applications include chargers and adapters. The AP3983R with built-in MOSFET, regulates the output voltage and current in the primary side by piecewise Pulse Frequency Modulation (p-PFM) in discontinuous conduction mode (DCM).
