G1135A
Description
G1135A is a high performance 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 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 pensation. 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. G1135A offers power on soft start control and protection coverage with auto-recovery features including Cycle-by-Cycle current limiting,VDD...
