Product Description

-Data Sheet

* General Description 

SF1560  is   a  high   performance,  highly   integrated current  mode  PWM  controller  for  medium  to  large offline flyback converter applications.  
In SF1560, the PWM switching is internally trimmed to tight range. To improve EMI performance, the IC integrates   frequency  shuffling   function   to   reduce conduction EMI emission of a power supply.

The IC also  integrates   Constant  Power   Limiting  block   to achieve  constant  output  power  limit  from  90VAC  to 264VAC.  
Under  light  load  conditions,  a  green  mode  function can  continuously  decrease  the  switching  frequency. Under zero-load conditions, the power supply enters into  burst  mode  and  provides  excellent   efficiency without  audio   noise  generated.  

This  green  mode function enables power supplies to meet international power conservation requirements. SF1560 integrates functions and protections of Under Voltage    Lockout    (UVLO),    VDD    Over    Voltage Protection (OVP), Soft Start, External Programmable Over  Temperature  Protection  (OTP),  Cycle-by-cycle Current Limiting (OCP), Over Load Protection (OLP), Pins   Floating    Protection,    RI   Pin    Short-to-GND Protection, GATE Clamping, VDD Clamping, Leading Edge Blanking (LEB).  
In SF1560, the OTP and VDD OVP is latch plug-off protection.  The  other  protection  functions  are  auto-recovery mode protection. SF1560 is available in SOP-8 and DIP-8 packages
