Description
The STEVAL-ILL066V2 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: the STEVAL-ILL066V2 can achieve a 92% efficiency at full load while maintaining a low < 250 mW power consumption in idle periods and less than 500mW during failure (open or short). 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-ILL066V2 evaluation board provides DALI, insulated 0-10 and UART physical communication interfaces, with all communication managed by the STLUX385A device. The flexibility of the STLUX385A device and the UART interface allow quick connection of the STEVAL-ILL066V2 to various interfaces such as Wi-Fi, power line modems, NFC, Bluetooth® and Zigbee®.
