OB2216 Primary-Side Regulation PWM Power Switch GENERAL DESCRIPTION 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 figure below. In CC control, the current and output power setting can be adjusted externally by the sense resistor Rs at CS pin. In
