features include EMI filtering, transient protection and lamp FAULT protection.
International Rectifier (IR) and Microchip Technology Inc. worked together to design a DALI type ballast. An application note is provided here, and the corresponding reference design is available from IR (see page 10 for ordering information).
This document describes many of the details within the design of the ballast and some of the basics to DALI. However, this document does not describe all the details contained within the DALI specification. The reader should be familiar with DALI and international standard EN60929.
