Specifications

Absolute maximum ratings indicate sustained limits beyond which damage to the device may occur. All voltage parameters are absolute voltages referenced to COM, all currents are defned positive into any lead. The thermal resistance and power dissipation ratings are measured under board mounted and still air conditions.

Description

The IRS2168DSPbF is a fully integrated, fully protected 600 V ballast control IC designed to drive all types of fluorescent lamps. The IRS2168DSPbF is based on the popular IR2166 control IC with additional improvements to increase ballast performance. The PFC circuitry IRS2168DSPbF operates in critical conduction mode and provides high PF, low THD and DC bus regulation. The IRS2168DSPbF 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.
