STEVAL-ILL057V1

200 W, digital 4-LED channels demonstration board with STLUX385A-controlled current regulation and dimming
  • active Active

The STEVAL-ILL057V1 product evaluation board is a complete and configurable solution for managing four independent high-brightness LED channels using the STLUX385A digital controller. The STLUX385A is part of STMicroelectronics’ Masterlux™ family and embeds advanced peripherals tailored to generate high resolution PWM signals (SMED).

The STEVAL-ILL057V1 implements inversed buck topology to drive each LED channel. The SMED technology integrated in the STLUX385A regulates the LED current, exploiting the fixed off-time (FOT) principle. Each channel can generate output current in the range of 250 mA to 1 A.

The number of LEDs, the current and the PWM dimming point can be set through the command interpreter, accessible via the serial interface. Dimming can also be manually adjusted via the three on-board buttons.

The evaluation board can be optionally controlled via a DALI interface. The DALI connection board is available separately (part number STEVAL-ILM001V1). The STLUX385A DALI software drivers and application firmware are available.
