RS2112 High Precision CC/CV Primary-Side PWM Power Switch

RS2112 Description

RS2112 High Precision CC/CV Primary-Side PWM Power Switch .
RS2112 is a high performance offline PSR controller for low power AC/DC charger and adapter applications.

RS2112 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

RS2112 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
