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 STLUX385A based (ZVS) LC resonant stage. The high precision High efficiency (92%) dimming is adjusted using a primary side regulation (PSR) control technique. Primary side controlled Up to 100 W (100 V at 1 A or 200 V at 0.5 A) The LED brightness can be dimmed by controlling the LED current down to a very low level. Single isolated output suitable for LED connection. The STEVAL-ILL066V1 evaluation board provides all the physical communication Wide input voltage range: 90 V to 265 V AC interfaces such as a DALI, insulated 0-10 and Adjustable LED current and dimming UART. All the communication is managed by the Output resolution: 11-bit equivalent. STLUX385A device. The UART interface and STLUX385A flexibility allow to quickly connect the IDLE mode power consumption: < 200 mW STEVAL-ILL066V1 to alternative interfaces such Real-time fault detection and protection as Wi-Fi, power line modems, Bluetooth and (e. g.: short- or open circuit) Zigbee . (Previous part number was Remote control via DALI, 0 - 10 V, UART STEVAL385LEDPSR).
