IRS2166DSPBF

Lighting, Ballast Controllers Overview

The IRS2166DSPBF is a fully integrated, protected 600V ballast control IC designed to drive all types of fluorescent lamps. It combines PFC, ballast control, and half-bridge driver functions in a single component. The device supports critical conduction mode boost type PFC without requiring a current sense resistor. It features programmable preheat frequency, preheat time, run frequency, over-current protection, end-of-life protection, and dead time. Comprehensive protection includes lamp strike failure, filament failures, DC bus undervoltage reset, and an automatic restart function.
