Data brief
Description
The STEVAL-ILL066V1 evaluation board is a
complete and configurable solution that efficiently
controls a single dimmable high brightness LED
string using the STLUX385A digital controller.
The LED efficiency is high during all stages of
dimming and the STEVAL-ILL066V1 can achieve
a 92% efficiency during full load while maintaining
a low < 200 mW power consumption during idle
periods.
The STLUX385A device handles a primary side
regulated power conversion stage as well as all
the supported communication links.
The power conversion stage consists of a PFC
regulator followed by a “Zero Voltage Switching”
(ZVS) LC resonant stage. The high precision
dimming 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.
The STEVAL-ILL066V1 evaluation board
provides all the physical communication
interfaces such as a DALI, insulated 0-10 and
UART. All the communication is managed by the
STLUX385A device. The UART interface and
STLUX385A flexibility allow to quickly connect the
STEVAL-ILL066V1 to alternative interfaces such
as Wi-Fi, power line modems, Bluetooth^® and
Zigbee^®. (Previous part number was
STEVAL385LEDPSR).
