◆  Primary-side  Sensing  and  Regulation  Without  TL431  and  Opto-coupler
◆  Programmable  CC  Regulation
◆  Adjustable  Constant  Current  and  Output  Power  Setting
◆  Built-in  Secondary  Constant  Current  Control  with  Primary  Side  Feedback
◆  Built-in  Adaptive  Current  Peak  Regulation
◆  Built-in  Primary  winding  inductance  compensation
◆  Power  on  Soft-start
◆  Cycle-by-Cycle  Current  Limiting
◆  Built-in  Leading  Edge  Blanking  (LEB)
◆  VDD  Under  Voltage  Lockout  with  Hysteresis  (UVLO)
◆  VDD  OVP
◆  VDD  Clamp
◆  Available  in  DIP8  packages,  RoHS  compliant

Applications:

Low  Power  AC/DC  offline  SMPS  for
◆  LED  applications
