FA5531 - (FA5530 - FA5532) Quasi-Resonant IC

Download the FA5531 datasheet PDF. This datasheet also covers the FA5530 variant, as both devices belong to the same (fa5530 - fa5532) quasi-resonant ic family and are provided as variant models within a single manufacturer datasheet.

Key Features

  • Features.
  • Internal start-up circuit with 500V rating and low frequency operation achieves 140mW input at no load.
  • Small Output Capacitance : Linearly reduced frequency for lighter load causes small ripple voltage.
  • Suitable for Low Noise and High Efficiency about 90%.
  • Line-up of 3 types for maximum frequency and OLP 5530: 65kHz max. ,16Vmax. -VCC,Auto-restart OLP 5531:130kHz max. ,28Vmax. -VCC,Auto-restart OLP 5532:130kHz max. ,28Vmax. -VCC,Timer-Latched OLP.
