OB3636A High PF, Low THD Offline CV Controller GENERAL DESCRIPTION OB3636A 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 fast start-up time requirement.
