G1135 is High Precision CC/CV Primary-Side PWM Power Switch manufactured by Global Semiconductor.
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...
