www.DataSheet4U.com Data Sheet No. PD60292 IRS2166D(S)PbF PFC + BALLAST CONTROL IC Features PFC, ballast control and 600 V half-bridge driver in one IC Critical-conduction mode boost-type PFC Programmable half-bridge over-current protection Programmable preheat frequency Programmable deadtime Programmable preheat time Programmable run frequency End-of-life window comparator pin Internal up/down current-sense fault counter DC bus undervoltage reset Lamp removal/auto-restart shutdown pin Internal bootstrap MOSFET Internal 15.6 V zener clamp diode on VCC Micropower startup (250 µA) Latch immunity and ESD protection Description The IRS2166D is a fully integrated, fully protected 600 V ballast control IC designed to drive all types of fluorescent lamps. The IRS2166D is based on the popular IR2166 control IC with additional improvements to increase ballast performance. PFC circuitry operates in critical conduction mode and provides high PF, low THD, and DC bus regulation. The IRS2166D features include programmable preheat and run frequencies, programmable preheat time, 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. System Features Improved VBUS regulation voltage tolerance Increased SD pin shutdown voltage threshold hysteresis Changed EOL pin internal 2.0 ...
