Description
This IC takes full advantage of IR’s patented ballast and high-voltage technologies to realize a simple, high-
performance dimming ballast solution. A single high-voltage pin senses the half-bridge current and voltage
to perform necessary ballast protection functions. The DC dim input voltage reference and the AC lamp
current feedback have been coupled together allowing a single pin to be used for dimming. Combining these
high-voltage control algorithms together with a simple dimming method in a single 8-pin IC results in a large
reduction in component count, an increase in manufacturability and reliability, a reduced design cycle time,
while maintaining high dimming ballast system performance
