      • SF6072 is a high performance, highly integrated DCM(Discontinuous Conduction Mode)Primary Side Regulation (PSR)controller for Offline LED lighting applications. It has built-in power BJT, which can further lower system cost. 
        SF6072 has built-in proprietary NC-Cap/PSRTM control for CV control, which eliminates external compensation or filtering capacitor, It has built-in cable drop compensation function, which can provide excellent CV performance. SF6072 uses Multi Mode Control to improve efficiency and reliability and to decrease audio noise energy @ light loadings. The IC can achieve less than 70mW standby power.  
        SF6072 integrates proprietary "Zero-Output startup" control to achieve startp when output is near zero voltage. The IC also has proprietary "Smart Output Short protection", which can limit maximum power when output is short circuit.  
        SF6072 integrates functions and protections of FB Short protection, Under Voltage Lockout (UVLO), VDD over Voltage Protection (VDD OVP), Soft start, Cycle-by-cycle Current Limiting (OCP), Pins Floating Protection, VDD Clamping. 
        SF6072 is available in SOIC-7 packages.
