RS2112 Datasheet (PTC) - High Precision CC/CV Primary-Side PWM Power Switch

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.

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 a
