Application Note: SY5072B Single-Phase Transition-Mode PFC Controller.

The SY5072B is a constant voltage Transition-Mode boost controller with Power Factor Correction (PFC) function. Constant ON Time control is applied to achieve high PF and low THD without multiplier. It drives the Boost converter in the Quasi-Resonant mode for high efficiency and better EMI performance. It adopts special design to achieve quick start up and reliable protection for safety requirement.
Valley Turn-on to Achieve Low Switching Losses.
Frequency Reduce in Light Load.
