SY5072B Overview
Features 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.
