Product Overview

STEVAL-ILL010V1 is a high intensity LED dimming driver evaluation board based on the L6902. This evaluation board is designed around an L6902D based DC/DC converter with dimming interface. It board implements both of two well known dimming methods like analog current control and average current control by PWM. While there is only a single dimming input connector on the board, it can be used for both dimming methods. A signal between 0V and 3.3V should be used for analog (peak current) dimming. When the dimming pin is grounded (0V), the 350mA maximum output current is provided. Likewise, when 3.3V is applied to the pin, the current provided is zero and the LED is off. The second dimming method implemented on this board is PWM control of average LED current. This control requires a digital PWM signal (with an amplitude of either 3.3V or 5V) between the dimming pin and the ground pin. Varying the dutycycle on the board will then change the brightness of the LED.
