Product Description

-Data Sheet

* General Description 
 

SF5938  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.
SF5938 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.SF5938 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. 
SF5938  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.
