UC3853 Datasheet | Unisonic Technologies

UNISONIC TECHNOLOGIES CO., LTD Advance LINEAR INTEGRATED CIRCUIT CURRENT MODE PWM CONTROLLER FOR FORWARD AND FLYBACK APPLICATIONS - DESCRIPTION The UTC UC3853 is a high performance current mode PWM controller ideally suited for low standby power. Low VDD startup current make the power reliable on startup design and a large value resistor could be used to minimize the standby power. At no load condition, the IC operates in power-saving mode for lower standby power, decreasing frequency for Higher conversion efficiency at light load condition. It contains protection with automatic recovery including OLP, OCP, VCC OVP, BNO and OTP. To protect the power MOSFET, Gate-drive output is...
