Description: PWM CONTROLLER

Features

* Primary‐side sensing and regulation without A431 and opto‐coupler
* High precision constant voltage and current regulation at universal AC input
* Multi‐mode PWM/PFM operation for efficiency improving
* Integrated 2A 650V MOSFET
* Good dynamic response with synchronous rectifie

Applications

* It operates in primary‐side sensing and regulation. Consequently, opto‐coupler and A431 could be eliminated. Proprietary Constant Voltage (CV) and Constant Current (CC) control isintegrated as shown in the figure below. In CC control, the current and output power setting can be adjusted externally
