Description
The IR2167 Demo Board is a high efficiency, high power factor, fixed output electronic ballast de-
signed for driving rapid start fluorescent lamp types. The design contains an EMI filter, active power
factor correction and a ballast control circuit using the IR2167. This demo board is intended to ease
the evaluation of the IR2167 Ballast Control IC, demonstrate PCB layout techniques and serve as an
aid in the development of production ballast’s using the International Rectifier IR2167.
