STEVAL385LED4CH

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

The STEVAL385LED4CH demonstration board is a complete and configurable solution to manage four independent high-brightness LED channels using the STLUX385A digital controller. The STLUX385A is a part of the STMicroelectronics®STLUX™ product family and embeds advanced peripherals tailored to generate high resolution PWM signals (SMED).

The STEVAL385LED4CH device implements inversed buck topology to drive each LED channel. The SMED technology integrated in the STLUX385A device regulates the LED current, exploiting the fixed-off-time (FOT) principle. Each channel can output current in the range of 250 mA to 1 A.

The number of LEDs, the current and the PWM dimming working 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 demonstration 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.

This demonstration board is available also with an order code STEVAL-ILL057V1.
