G1132F High Precision CC/CV Primary-Side PWM Power Switch ANALOG PWM IC 1.0 General Description G1132F is a high performance offline PWM Power switch for low power AC/DC charger and adaptor applications up to 5W.It operates in primary-side regulation. Consequently, opto-coupler and TL431 could be eliminated. Proprietary Constant Voltage (CV) and Constant Current (CC) control is integrated as shown In the Fig.1. In CC control,the current and output power setting can be adjusted externally by the sense resistor RS at CS pin. In CV control, multi-mode operations are utilized to achieve high performance and high efficiency. In addition, good load regulation is achieved by the built-in cable drop compensation.
