  • SF5948 is a high performance, highly integrated DCM (Discontinuous Conduction Mode) Primary Side Regulation (PSR) power switch for offline small power converter applications. It can achieve less than ±4% CV/CC precision. dDj嘉泰姆


  •   SF5948 has built-in proprietary NC-Cap/PSR-IITM 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. 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 70mW standby power. dDj嘉泰姆


  •  SF5948 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. SF5948 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. dDj嘉泰姆


  •  SF5948 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. dDj嘉泰姆


  •   SF5948 is available in DIP8 package.dDj嘉泰姆
