AN2982
Application note
1 x 54 W T5 fluorescent lamp ballast in wide input voltage range
using the L6585DE - STEVAL-ILB005V2

Introduction
This application note describes the STEVAL-ILB005V2 demonstration board equipped with
the L6585DE lighting controller, STD7NM50N MOSFETs and an STTH1L06 Shottky diode
able to drive a 54 W linear T5 fluorescent lamp in a wide input voltage range (88 - 277 Vac).
The design steps, schematic and board performance are also given.
The L6585DE lighting controller embeds both the PFC stage and ballast stag
