産品介紹

SF6773V is a high performance, highly integrated QR(Quasi Resonant Mode) and Primary Side Regulation(PSR) power switch for offline small power converter applications. SF6773V 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 compensation function to achieve excellent CV performance. SF6773V uses Multi Mode Control to improve efficiency and reliability and to decrease audio noise energy @ light loadings. SF6773V also integrates the function of “Max. Frequency Clamping @ Output Short Circuit” to limits power MOSFET Vds spike when output short circuits occurs. SF6773V integrates functions and protections of FB Short Protection, Under Voltage Lockout (UVLO),VDD Over Voltage Protection (VDD OVP), Output Over Voltage Protection (Output OVP), Soft Start,Cycle-by-cycle Current Limiting (OCP), Pin Floating Protection, VDD Clamping. SF6773V is available in SOP7 package.
