OB3636
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 ponents 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. Quasi-resonant (QR) operation and clamping frequency greatly improves the system efficiency. The advanced to start-up technology is used to meet the start-up time requirement (<0.5s). l OB3636 offers prehensive protection including open loop protection, short circuit protection, tia cycle-by-cycle...
