Product Summary

The IR2166SPBF 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. The IR2166SPBF features include programmable preheat and run frequencies, programmable preheat time, programmable dead-time, programmable over-current protection, and programmable end-of-life protection. Comprehensive protection features such as protection from failure of a lamp to strike, filament failures, end-of-life protection, DC bus undervoltage reset as well as an automatic restart function, have been included in the design. The IR2166SPBF is available in both 16-lead PDIP and 16-lead (narrow body) SOIC packages.
