Application note

100 W LED street lighting application using STLUX385A

Francesco Ferrazza and Ambrogio D’Adda

Introduction

The STEVAL-ILL066V1 demonstration board is a complete and configurable solution that

manages a single high brightness LED string using the STLUX385A digital controller and

two stages of power conversion. The application consists of a PFC regulator followed by a

zero voltage switching (ZVS) LC resonant stage. The LED current is adjusted using a

primary side regulation (PSR) control technique. The LED brightness can be dimmed by

controlling the LED current down to a very low level. Communication interfaces like DALI

and UART are present, as well as an insulated 0 - 10 control input. This application note

describes the use of the STEVAL-ILL066V1 demonstration board, the hardware design and

the firmware implementation. A real measurement is also described. For complete

information on the STLUX385A digital controller, please refer to the STLUX385A datasheet.

Danger:

High voltage is present on the PSR-ZVS demonstration

board.

Caution:

This board shall be used by qualified and knowledgeable people due to internal high

voltage. The user shall take great care when handling the demonstration board, even when

no power is supplied.
