Data Sheet No. PD60198-C IR2166(S) PFC & BALLAST CONTROL IC Features • PFC, Ballast control and half-bridge driver in one IC • Critical conduction mode boost type PFC • No PFC current sense resistor required • Programmable preheat frequency • Programmable preheat time • Programmable run frequency • Programmable over-current protection • Programmable end-of-life protection • Programmable dead time • Internal ignition ramp • Internal fault counter • DC bus under-voltage reset • Shutdown pin with hysteresis • Internal 15.6V zener clamp diode on Vcc • Micropower startup (150µA) • Latch immunity and ESD protection 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 include programmable preheat and run frequencies, programmable preheat time, programmable dead-time, programmable over-current protection, and programmable endof-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.

All voltage parameters are absolute voltages referenced to COM, all currents are defined positive into any lead. The thermal resistance and power dissipation ratings are measured under board mounted and still air conditions.
