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.

Note:
Thick traces represent high-frequency, high-current paths.
Lead lengths should be minimized and power and IC grounds should be separated to avoid high-frequency

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 defined 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 V
CC
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 V
CLAMP
specified in the electrical characteristics section.
Recommended Operating Conditions
For proper operation the device should be used within the recommended conditions.
