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.

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-Y Cap design. Features.
Primary-side Sensing and Regulation With No 431 and Opto-coupler.
Multi-mode operation for High Efficiency.
Programmable CV and CC Regulation.
Adjustable.
