General Description

Pro 1 FB 2 ， CS 3 GND 4 GATE 5 VCC 6 NC 7 HV 8 X Cap NEM Confidential 4 PSU Specifications Input Characteristics Rated Input Voltage: 90~264Vac Frequency Range: 47~63Hz: Efficiency: Eff.> 87.4% @115V/230Vac, Po=36W BI/Bo:85Vac/75Vac;BO Delay time:

Key Features

  • to enhance the performance of off-line power supply in SOP-8 package. With the adjustable OPP function integrated in HV pin, it is easy to design the over power protection well under high/low line condition.
  • Turbo boost technology during over load or peak load condition Power boost in a specific period.
  • HV startup with low leakage current, Brown out function. Increased frequency during peak load operation to avoid.
  • Safety Protection: Vcc-GND short test, LPS limita.
