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-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.
