Overview
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.
The system operating frequency reduces linearly from heavy load to light load in each interval ...
