STEVAL-ILL066V2 STMicroelectronics

STEVAL-ILL066V2 100 W LED street lighting evaluation board using the STLUX385A digital controller Features based on STLUX385A digital controller 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: < 250 mW real-time fault detection and protection (short-circuit or open circuit) remote control via: DALI ed.2.0 0 - 10 V UART RoHS compliant 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. Product summary The LED efficiency is high during all stages of dimming: the STEVAL-ILL066V2 can STEVAL-ILL066V2 STEVAL- achieve a 92% efficiency at full load while maintaining a low < 250 mW power evaluation board ILL066V2 consumption in idle periods and less than 500mW during failure (open or short). STLUX385A digital STLUX385A The STLUX385A device handles a primary side regulated power conversion stage as controller for lighting well as all the supported communication links. and power conversion applications 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 STSW-ILL066V2 STSW- primary side regulation (PSR) control technique. firmware ILL066V2 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 .
