UC3853 Datasheet Current Mode Pwm Controller

Manufacturer: Unisonic Technologies

Overview: UNISONIC TECHNOLOGIES CO., LTD UC3853 Advance LINEAR INTEGRATED CIRCUIT CURRENT MODE PWM CONTROLLER FOR FORWARD AND FLYBACK APPLICATIONS.

General 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.
