Description
The IRS2168D is a fully integrated, fully protected 600 V
ballast control IC designed to drive all types of fluorescent
lamps. The IRS2168D 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 IRS2168D 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-ot-lite protection. Comprehensive
protection features such as protection from failure of a lamp
to strike, Filament failures, end-of-lite protection, DC bus
undervoltage reset as well as an automatic restart function,
have been included in the design.

Absolute Maximum Ratings
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.

Note 1: This IC contains a Zener clamp structure between the chip Vcc and COM which has a nominal breakdown
voltage of 15.6 V. This supply pin should not be driven by a DC, low impedance power source greater than the VCLAMP
specified in the Electrical Characteristics section.
