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

DescriptionThe STEVAL-ILL066V2 evaluation board is a complete and configurable solution thatefficiently controls a single, dimmable, high-brightness LED string using theSTLUX385A digital controller.

The LED efficiency is high during all stages of dimming: the STEVAL-ILL066V2 canachieve a 92% efficiency at full load while maintaining a low < 250 mW powerconsumption in idle periods and less than 500mW during failure (open or short).

The STLUX385A device handles a primary side regulated power conversion stage aswell as all the supported communication links.

The power conversion stage consists of a PFC regulator followed by a “Zero VoltageSwitching” (ZVS) LC resonant stage. The high precision dimming is adjusted using aprimary side regulation (PSR) control technique.

The LED brightness can be dimmed by controlling the LED current down to a verylow level.

The STEVAL-ILL066V2 evaluation board provides DALI, insulated 0-10 and UARTphysical communication interfaces, with all communication managed by theSTLUX385A device.The flexibility of the STLUX385A device and the UART interface allow quickconnection of the STEVAL-ILL066V2 to various interfaces such as Wi-Fi, power linemodems, NFC, Bluetooth® and Zigbee®.
