The STMicroelectronics STEVAL-ILL079V1 is an inverting buck-boost LED driver evaluation board. The board features the LED6000 current regulator. The LED600 is a monolithic current source with dimming capability, for driving high-power LEDs. The device offers a wide input voltage range, enabling you to use alternative topologies on the board, for example buck-boost.
Eight white LEDs (max 30 V) are powered via a 0.5 A programmed current. Digital dimming is achieved on the board by driving the DIM pin. External circuitry can be added to achieve the necessary level shifting. You can also adjust the current limit threshold and switching frequency on the board, to suit your chosen application.
