G1135 High Precision CC/CV Primary-Side PWM Power Switch ANALOG PWM IC 1. General Description G1135 is a high performance offline PWM Power switch for low power AC/DC charger and adaptor application. 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 res.

G1135 High Precision CC/CV Primary-Side PWM Power Switch ANALOG PWM IC 1. General Description G1135 is a high performance offline PWM Power switch for low power AC/DC charger and adaptor application. 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. Device operates in PFM in CC mode as well at large load condition and it operates in PWM with frequency reduction at light/medium load. G1135 offers power on soft start control and protection coverage with auto-recovery features including Cycle-by-Cycle current limiting, VDD OVP, VDD clamp and.
