Perfect control over RBG LEDs

LED Driver 3 click is an RGB LED driver, capable of driving RGB LEDs with up to 30mA per segment, via the digital I2C interface. It comes with an RGB LED onboard, and is capable of displaying a palette of 32768 colors. It features an integrated circuit with three independent LED driver sections and a programmable gradual dimming control, which gives a smooth dimming effect. Heat dissipation is taken to the minimum, due to a fact that the used driver IC works with up to 94% efficiency.

LED Driver 4 click is a form of a high-efficiency boost converter that is ideally suited for driving an array of white LEDs. The driver has the ability to dim the connected LED array, without producing any noise on the output. The Click board™ is capable of driving a LED array with up to 26V, providing a constant current to the LED segments. The LED segments are connected in series between the output terminals, which results in an even current distribution, thus providing a uniform brightness of each LED. A built-in soft-start function prevents large inrush current. Output open LED circuit, thermal, and undervoltage protection, provide a reliable operation.
