Overview
A D V A N CNEEDW IPNRF ODRUMCATT I O N AP3983R PRIMARY SIDE REGULATED SWITCHING MODE POWER SUPPLY CONTROLLER Description 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).
The system operating frequency reduces linearly from heavy load to light load in each interval of the p-PFM, and enters constant current mode when the load current equals to the maximum system output current.
The AP3983R provides accurate constant voltage (CV), constant current (CC) and outstanding dynamic performance without requiring an opto-coupler.
It also eliminates the need for loop compensation circuitry while maintaining stability.
The AP3983R has a built-...
