Packages
The IR2167 is a fully integrated, fully protected 600V ballast control IC designed to
drive all types of fluorescent lamps. PFC circuitry provides for high PF, low THD and
DC Bus regulation. Externally programmable features such as preheat time & fre-
quency, ignition ramp characteristics, and running mode operating frequency provide a
high degree of flexibility for the ballast design engineer. Comprehensive protection
features such as protection from failure of a lamp to strike, filament failures, low AC
line conditions, thermal overload, or lamp failure during normal operation, as well as
an automatic restart function, have been included in the design. The heart of the
ballast control section is a variable frequency oscillator with externally programmmable
deadtime. Precise control of a 50% duty cycle is accomplished using a T-flip-flop.
