G1135A, High Precision CC/CV Primary-Side PWM Power Switch

G1135A High Precision CC/CV Primary Side PWM Controller ANALOG PWM IC 1.General .
G1135A is a high performance offline PWM Power switch for low power AC/DC charger and adaptor applications.

Features

* including Cycle-by-Cycle current limiting,VDD OVP,VDD

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
