SF6020 is a high performance, highly integrated DCM（Discontinuous Conduction Mode）Primary Side Regulation （PSR）controller for Offline LED lighting applications. It can achieve less than ±4% CV /CC precision.
SF6020 has built-in proprietary NC-Cap/PSRTM control for CV control, which eliminates external compensation or filtering capacitor, It also has built-in cable drop compensation function, which can provide excellent CV performance. The IC uses Multi Mode control to improve efficiency and reliability and to decrease audio noise energy @ light loSF6020 integrates proprietary "Audio Noise Cancellation" control for audio noise free operation. The IC has built-in "Fast Dynamic Response" control to meet USB charge requirements.SF6020 also 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.
SF6020 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.
SF6020 is available in SOT23-5 packages.
