GENERAL DESCRIPTION
FEATURES
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. 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 comprehensive protection including open loop protection, short circuit protection, tia cycle-by-cycle current limiting, built-in leading edge blanking, VDD under voltage lockout (UVLO), etc. fiden OB3636 is offered in SOT23-6 package.
