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.
