G1135P Datasheet - Global Semiconductor

G1135P ANALOG PWM

G1135P is a high performance offline PWM Power switch for low power AC/DC charger and adaptor applications up to 12W.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 .

G1135P Features

* including Cycle-by-Cycle current limiting, VDD OVP, VDD clamp and UVLO. Excellent EMI performance is achieved with frequency jitter technique. Fig.1. Typical CC/CV Curve ANALOG PWM IC Features

* 5% CV and CC Regulation at Universal AC input

* Primary-side Regulation Without TL431 and Opto-
