Product Summary

The IRS2168DSTRPBF is a fully integrated, fully protected 600 V ballast control IC designed to drive all types of fluorescent lamps. The IRS2168DSTRPBF is based on the popular IR2166 control IC with additional improvements to increase ballast performance. The PFC circuitry operates in critical conduction mode and provides high PF, low THD and DC bus regulation. The IRS2168DSTRPBF features include programmable preheat and run frequencies, programmable preheat time, programmable PFC over-current protection, closed-loop half-bridge ignition current regulation, 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.
