NEW PRODUCT A Product Line of Diodes Incorporated APS39903 PUMP EXPRESSTM COMPATIBLE AC/DC PSR SWITCHER Description Pin Assignments The APS39903 is a high accuracy and low cost switching mode power supply switcher for battery charger/adapter applications. It is consists of a primary side regulation controller and a high voltage transistor. 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). The switcher uses adaptive source current to optimize driving current to reduce driving loss.
