IR2166S - PFC & BALLAST CONTROLLER

Datasheet Summary

Description

The IR2166 is a fully integrated, fully protected 600V ballast control IC designed to drive all types of fluorescent lamps.

PFC circuitry operates in critical conduction mode and provides for high PF, low THD and DC Bus regulation.

Features

  • PFC, Ballast control and half-bridge driver in one IC.
  • Critical conduction mode boost type PFC.
  • No PFC current sense resistor required.
  • Programmable preheat frequency.
  • Programmable preheat time.
  • Programmable run frequency.
  • Programmable over-current protection.
  • Programmable end-of-life protection.
  • Programmable dead time.
  • Internal ignition ramp.
  • Internal fault counter.
  • DC bus under-voltage.
