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.
