2X36 W digital dimmable ballast with L6574 and ST7FDALI

Introduction
This document describes a high-efficiency, high power factor, low THD and digital dimming
electronic ballast designed to drive 2X36 W T8 tube lamps.
The system consists of three main blocks:
The high-frequency ballast includes an active power factor correction circuit based on the
L6562 for universal input voltage as well as a ballast control circuit based on the L6574. The
digital dimming is performed by interfacing the ST7FDALI microcontroller
