OB2211/OB2212 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 On-Bright proprietary frequency shuffling technique together with soft switching control at the totem pole gate drive output with No-Y cap design.
