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
RoHS compliant
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
noise problems.
