Configurable solution for managing four independent high-brightness LED channels

A complete and configurable solution for managing four independent high-brightness LED channels using the STLUX385A digital controller, the STMicroelectronics STEVAL-ILL057V1 digital LED Channel Evaluation Board is now available from Mouser stock. 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 250mA to 1A. 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.
