G1135A
G1135A is High Precision CC/CV Primary-Side PWM Power Switch manufactured by Global Semiconductor.
High Precision CC/CV Primary Side PWM Controller
ANALOG PWM IC
1. General 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...
