General Description
SF6022 is a high precision,highly integrated DCM(Discontinuous Conduction Mode)Primary Side Regulation(PSR) power switch for offline smallpower converter applications.It has built-in powerBJT, which can further lower system cost.
SF6022 has built-in proprietary NC-Cap/PSR-IITM control for CV control,which eliminates external compensation or filtering capacitor.It has built-incable 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.
SF6022 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.SF6022 also integrates proprietary "Zero-Output Startup"control to achieve startup when output is near zero voltage. The IC has proprietary "Smart Output Short
Protection", which can protect the system with large leakage inductance when output is short circuit.
SF6022 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), Pin Floating Protection, VDD Clamping.SF6022 is available SOP7 packages.
