Packages
The IR21571 is a fully integrated, fully protected 600V ballast control IC designed
to drive virtually all types of rapid start fluorescent lamp ballasts. Externally pro-
grammable features such as preheat time & frequency, ignition ramp characteris-
tics, and running mode operating frequency provide a high degree of flexibility for
the ballast design engineer. Comprehensive protection features such as protec-
tion from failure of a lamp to strike, filament failures, low dc bus 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 this control IC is a variable
frequency oscillator with externally programmable deadtime. Precise control of a
50% duty cycle is accomplished using a T-flip-flop. The IR21571 is available in both
16 pin DIP and 16 pin narrow body SOIC packages.
