STEVAL385LEDPSR

100W LED street lighting demonstration board using STLUX385A
  • NRND NRND

The STEVAL385LEDPSR demonstration 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 and the STEVAL385LEDPSR can achieve a 92% efficiency during full load while maintaining a low < 200 mW power consumption during idle periods.

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 STEVAL385LEDPSR demonstration board provides all the physical communication interfaces such as a DALI, insulated 0-10 and UART. All the communication is managed by the STLUX385A device. The UART interface and STLUX385A flexibility allow to quickly connect the STEVAL385LEDPSR board to alternative interfaces such as the Wi-Fi, power line modems, Bluetooth®and ZigBee®.

This demonstration board is available with an order code STEVAL-ILL066V1 now.
