Description: High Precision CC/CV Primary-Side PWM Power Switch

Features

* including Cycle-by-Cycle current limiting, VDD over voltage protection, feedback loop open protection, short circuit protection, built‐ in leading edge blanking, VDD under voltage lockout (UVLO), etc. FEATURES
* ±5% constant voltage regulation at universal AC input
* High precision constant

Applications

* It operates in primary‐ side sensing and regulation. Consequently, opto-coupler and TL431 could be eliminated. Proprietary Constant Voltage (CV) and Constant Current (CC) control is integrated as shown in the figure below. In CC control, the current and output power setting can be adjusted external
