OB2216, OB2216_On, Primary-Side Regulation PWM Power Switch
OB2216 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.
Proprietary Constant Voltage (CV) and Constant Current (CC) control is integrated as shown in the
OB2216 Features
* including Cycle-by-Cycle current limiting, VDD clamp and UVLO. Excellent EMI performance is achieved with On-Bright proprietary frequency shuffling technique together with soft switching control at the totem pole gate drive output. FEATURES
* Primary-side Sensing and Regulation Without TL43
