OB3636MP

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 single stage converter. It significantly simplifies the CV system design by eliminating the secondary side feedback components and the opto-coupler.      The proprietary CV control scheme is used and the system can achieve high power factor with constant on-time control scheme. Quasi-resonant (QR) operation and clamping frequency greatly improves the system efficiency. The advanced start-up technology is used to meet the start-up time requirement (0.9) Low THD (
