SF6070J is a high performance, highly integrated DCM（Discontinuous Conduction Mode）Primary Side Regulation （PSR）controller for Offline LED lighting applications. It can directly drive power BJT, which can further lower system cost.
SF6070J 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 loadings. The IC can achieve less than 90mW standby power.
SF6070J 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.SF6070J 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.
SF6070J 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.
SF6070J is available in SOT23-5 and SOT23-6 packages.
