LD7833V 01/20/2015 High Power Factor Primary Side Flyback LED Controller With TRIAC Dimming REV. 00 General Description The LD7833V is a primary side regulation Flyback controller with power factor for TRIAC dimmable LED application. The LD7833V provides constant current (CC) operation requiring neither photo-coupler nor secondary control circuit. It minimizes the components counts in a tiny package. Those make it easy to design for cost- effective applications. With high voltage start-up technology, high power factor and TM control, the start-up time and MOSFET switching losses could be minimized efficiently.
