Description
The IRPLDIM1E is a high efficiency, high power factor, dim-
ming electronic ballast designed for driving rapid start fluo-
rescent lamp types. The design contains an EMI filter, ac-
tive power factor correction and a ballast control circuit us-
ing the IR21592. This demo board is intended to ease the
evaluation of the IR21592 Dimming Ballast Control IC,
demonstrate PCB layout techniques and serve as an aid
in the development of production ballast’s using the IR21592.
