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. The IR2166 features in-
clude programmable preheat and run frequencies, programmable preheat time, pro-
grammable 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 IR2166 is
available in both 16-lead PDIP and 16-lead (narrow body) SOIC packages.
