8561 - POWER FACTOR CORRECTOR

General Description

The UTC 8561 is a Power Factor Corrector, which can work in wide input voltage range applications (from 85V ~ 265V) with an excellent THD.

It has very low start up current (about 50 uA) and a disable function on the ZCD pin, which is designed to keep lower current consumption in stand by mode.

Key Features

  • S.
  • 1% Precision (@ TJ = 25°C) Internal Reference Voltage.
  • Output Overvoltage Protection.
  • Very Low Power Start-Up Current.
  • Very Low Operating Supply Current.
  • Current Sense Filter On Chip.
  • Disable Function (with ZCD Pin).
  • Transition Mode Operation.
  • Gate Driving Current: ± 400mA.
