OB3636
High PF, Low THD Offline CV Controller
GENERAL DESCRIPTION
FEATURES
OB3636 is a flyback controller with high power factor, low THD and high constant voltage(CV) precision. It can achieve low system cost for an isolated application by primary side control in a
High PF (>0.9) Low THD (<10%) High precision constant voltage regulation
single stage converter. It significantly simplifies the CV system design by eliminating the secondary side feedback components and the opto-coupler.
Fast start-up (<0.5s) Primary-side sensing and regulation without
TL431 and opto-coupler
The proprietary CV control scheme is used and Low system cost and high efficiency
the system can achieve high power factor with constant on-time control scheme.
