The LED Driver 4 Click Board™ is a form of a high-efficiency boost converter that is ideally suited for driving an array of white LEDs. The driver can 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. This results in 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 under-voltage protection, provide reliable operation.
