CURRENT MODE PWM CONTROLLER FOR FORWARD AND FLYBACK APPLICATIONS

The UTC UC3853 is a high performance current mode PWMcontroller ideally suited for low standby power. Low V DD startupcurrent make the power reliable on startup design and a largevalue resistor could be used to minimize the standby power. At noload condition, the IC operates in power-saving mode for Peak Current Mode Control Adjustable Switching Frequency Adjustable Soft−start Timer Adjustable Internal Ramp Compensation Jittering Frequency ±6% of the Switching Frequency Power-saving mode for high standby efficiency Auto−recovery Primary OCP with 10ms Fixed Delay Auto−recovery Brown−Out Dete;
