STMicroelectronics STEVAL-ILL066V2 Evaluation Board
STMicroelectronics STEVAL-ILL066V2 Evaluation Board is used to control a single dimmable, high-brightness LED string using the STLUX385A digital controller. The STEVAL-ILL066V2 achieves a 92% efficiency at full load and maintains low <250mW power consumption in idle periods. The STEVAL-ILL066V2 also has >500mW during failure (open or short). The STMicroelectronics STEVAL-ILL066V2 Evaluation Board handles a primary side regulated power conversion stage and 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. LED brightness can be dimmed by controlling the LED current down to a very low level. The STMicroelectronics STEVAL-ILL066V2 Evaluation Board provides DALI, insulated 0-10, and UART physical communication interfaces, with all communication managed by the STLUX385A device.
