Description

The IRPLLNR2 is a high efficiency, high power factor, fixed output

electronic ballast designed for driving rapid start fluorescent lamp types. The design contains an EMI

filter, active power factor correction and a ballast control circuit using the IR21571. This demo board is

intended to ease the evaluation of the IR21571 Ballast Control IC, demonstrate PCB layout techniques

and serve as an aid in the development of production ballast’s using the International Rectifier IR21571.
