Description
OB2216 Primary-Side Regulation PWM Power Switch GENERAL .
OB2216 is an offline PWM Power switch for low power AC/DC charger and adaptor applications.
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
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 figure below. In CC control, the current and output power setting can be adjusted externall
