LOW COST POWER-SAVING MODE PWM CONTROLLER FOR FLYBACK CONVERTERS

The UTC UC3823 provides a CCM/valley switching mixedmode operation for better efficiency performance. The operationmode stays at CCM at heavy load, and switch to valley switching atlight load.The UTC UC3823 is a high performance current mode PWMcontroller ideally suited for low standby power. Low V Proprietary frequency hopping for Improved EMI performance Cycle-by-cycle current limiting CCM/Valley Switching Operation Fixed switch frequency 60~70kHz Dynamic peak current limiting for constant output power Built-in synchronized slope compensation Gate output voltage clamped at 16V Adjustable DC ;
