Overview
UNISONIC TECHNOLOGIES CO.
, LTD UC3816A CMOS IC LOW COST POWER-SAVING MODE PWM CONTROLLER FOR FLYBACK CONVERTERS  DESCRIPTION The UTC UC3816A provides a CCM/valley switching mixed mode operation for better efficiency performance.
The operation mode stays at CCM at heavy load, and switch to valley switching at light load.
The UTC UC3816A is a high performance current mode PWM controller ideally suited for low standby power.
Low VCC startup current make the power reliable on startup design and a large value resistor could be used in the startup circuit to minimize the standby power.
At no load condition, the IC operates in power-saving mode for lower standby power, decreasing frequency for ...
