IC ballast controller UC3872DW

A ballast is a device used to limit current in an electrical circuit. The most common application for a ballast is its use in fluorescent lamps to limit the current within the tube. An electronic ballast utilizes an electronic circuit to start and operate the lamps. The UC3872 IC minimizes switching losses and electromagnetic interference effects, and it precisely controls the minimum and maximum frequency with 1.2 percent accuracy. The UC3872 chip includes precisely designed circuits that increase efficiency and optimize circuit performance.
