Product Description

-Data Sheet

* 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.
