1. Description<br />
The <strong>IRPLLNR7</strong> Demo Board is a high efficiency, high power factor, fixed output electronic ballast<br />
designed for driving rapid start fluorescent lamp types. The design contains an EMI filter, active power<br />
factor correction and a ballast control circuit using the IRS2166D(S)PbF Ballast Control IC 1 . This<br />
demo board is intended to ease the evaluation of the IRS2166D, demonstrate PCB layout techniques<br />
and serve as an aid in the development of a production ballast using <strong>International</strong> <strong>Rectifier</strong>’s<br />
IRS2166D.<br />
