Overview
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 LED Driver 4 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.
Das LED Driver 4 Click Board™ ist eine Art Aufwärtswandler mit hohem Wirkungsgrad, der sich ideal für die Ansteuerung einer Reihe weißer LEDs eignet. Der Treiber kann die angeschlossene LED-Reihe dimmen, ohne dass am Ausgang Rauschen entsteht. Das LED Driver 4 Click Board™ kann eine LED-Reihe mit bis zu 26 V ansteuern und die LED-Segmente mit konstantem Strom versorgen.
Die LED-Segmente sind in Reihe zwischen den Ausgangsklemmen angeschlossen. Dies führt zu einer gleichmäßigen Stromverteilung und sorgt somit für eine gleichmäßige Helligkeit jeder LED. Eine integrierte Softstart-Funktion verhindert einen hohen Einschaltstrom. Offener LED-Ausgangsstromkreis sowie Überhitzungs- und Unterspannungsschutz sorgen für einen zuverlässigen Betrieb.
