IRS2166DC

Lighting, Ballast Controllers Overview

The IRS2166DC 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 one IC. The PFC circuitry operates in critical conduction mode to provide high power factor, low total harmonic distortion, and DC bus regulation. Key features include programmable preheat and run frequencies, programmable preheat time, programmable dead-time, and programmable over-current protection. Comprehensive protection includes lamp strike failure, filament failures, end-of-life protection, DC bus undervoltage reset, and an automatic restart function.
