Overview
| Topology | Power Factor Correction |
| Input voltage | 90-265 V |
| Switching frequency | 35-60 kHz |
| Output 1 | 10 V / 1 A |
| IC revision | 1 |
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.
