RS2123 High Precision CC/CV Primary-Side PWM Power Switch

RS2123 Description

RS2123 High Precision CC/CV Primary-Side PWM Power Switch .
RS2123 is a high performance offline PSR controller for low power AC/DC charger and adapter applications.

RS2123 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. TYPICAL CC/CV CURVE FEATURES
* ±5% constant voltage regulation at universal AC input

RS2123 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 externall
