Applications Note: SY5018B Single Stage Flyback and PFC Controller with CV Control Advanced Design Specification General Description Features SY5018B is a single stage Flyback and PFC controller targeting at Constant Voltage (CV) applications. Primary side control is applied to reduce the feedback circuit cost. It drives the Flyback converter in the Quasi-Resonant mode for high efficiency and achieves high power factor by constant on time control scheme. Adaptive PWM/PFM control is adopted for highest average efficiency. Ordering Information SY5018 □(□□)□ Temperature Code Package Code Optional Spec Code Ordering Number SY5018BFAC Package type Note SO8 ---- • Primary side CV control eliminates the opto-coupler.
