STEVAL-ILL066V1
100 W LED street lighting evaluation board using STLUX385A
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.
Features
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.
• STLUX385A based
• High efficiency (92%)
• Primary side controlled
• Up to 100 W (100 V at 1 A or 200 V at 0.5 A)
• Single isolated output suitable for LED
connection.
• Wide input voltage range: 90 V to 265 V AC
• Adjustable LED current and dimming
• Output resolution: 11-bit equivalent.
• IDLE mode power consumption: < 200 mW
• Real-time fault detection and protection
(e. g.: short- or open circuit)
• Remote control via DALI, 0 - 10 V, UART
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).
• RoHS compliant
