INTRODUCTION

This reference design is a high efficiency, high power factor, digital dimming electronic ballast designed to drive

rapid start fluorescent lamp types. The design contains an active power factor correction circuit for universal

voltage input as well as a ballast control circuit using the IR21592. The design also includes a PIC16F628

microcontroller and an isolation circuit for connecting to a Digitally Addressable Lighting Interface (DALI). Other

features include EMI filtering, transient protection and lamp fault protection.
