Overview

A D V A N CNEEDW IPNRF ODRUMCATT I O N AP3983E HIGH FREQUENCY PRIMARY SIDE POWER SWITCHER FOR OFF-LINE SMPS Description The AP3983E is high frequency power switcher for power supplies with better conversion efficiency, better voltage & current accuracy, and improved protection functions.
Typical applications include adapter for ADSL, home appliance power supply, LED lighting power supply and PC auxiliary power supplies.
The AP3983E with built in MOSFET, regulates the output voltage and current in the primary side by piece-wise Pulse Frequency Modulation (p-PFM) in discontinuous conduction mode (DCM).
The system operating frequency reduces linearly from heavy load to light load in each inte...
