GENERAL DESCRIPTION

SF6771S is a high performance, highly integrated QR (Quasi Resonant Mode) and Primary Side Regulation (PSR) controller for offline small power converter applications.

SF6771S has proprietary super-QR/PSRTM control for high efficiency and low EMI. The standby power is less than 75mW @230VAC. Thus, the IC can meet EPS Level 6 energy standard easily. The IC also has built-in cable drop compensation function, which can provide excellent CV performance.

SF6771S integrates functions and protections of Under Voltage Lockout (UVLO), VDD Over Voltage Protection (VDD OVP), Soft Start, Cycle-by-cycle Current Limiting (OCP), Pin Floating Protection, Gate Clamping, VDD Clamping.

SF6771S is available in SOT23-6 package
