RS2111 Datasheet (Orister) - Primary-Side Regulation PWM Power Switch

RS2111, Primary-Side Regulation PWM Power Switch

RS2111/RS2112 is an offline PWM Power switch for low power AC/DC charger and adaptor applications.

It operates in primary-side sensing and regulation.

Consequently, opto-coupler and TL431 could be eliminated from design.

Proprietary Constant Voltage (CV) and Constant Current (CC) control is integrat

RS2111 Features

* including Cycle-by-Cycle current limiting, VDD over-voltage clamp and UVLO, fail-safe protection for open loop fault condition. Excellent EMI performance is achieved with Orister proprietary frequency Jiggling technique together with soft switching control at the totem pole gate drive output with No
