OB3635A High PF, Low THD Offline LED Lighting Controller GENERAL DESCRIPTION FEATURES OB3635A is an offline LED lighting controller with high power factor, low THD and high constant current (CC) precision. It can achieve low system cost for an isolated lighting application by primary  High PF (>0.9)  Low THD (<10%)  High precision constant current regulation at side control in a single stage converter. It significantly simplifies the LED lighting system design by eliminating the secondary side feedback components and the opto-coupler. universal AC input  Fast start-up (<0.5s)  Primary-side sensing and regulation without TL431 and opto-coupler The proprietary CC control scheme is used and the system can achieve high power factor with constant on-time control scheme.
