SF6777 Overview
SF6777 is a high performance, highly integrated QR (Quasi Resonant Mode) and Primary Side Regulation (PSR) power switch for offline small power converter applications. SF6777 has proprietary super-QR/PSRTM control for high efficiency and low EMI, which can ensure system to meet EPS Level 6 energy standard. The IC also has built-in cable drop pensation function to achieve excellent CV performance.
