It has built-in power BJT, which can further lower system cost. SF6021 has built-in proprietary NC-Cap/PSR-II TM 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. SF6021 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. SF6021 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. SF6021 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. SF6021 is available SOP7 packages. TYPICAL APPLICATION AC IN DC Out 7 6 5 1 NC FB CS GND VDD 2 3 4 C C SF6021 Pin Configuration |
