Designing an Adjustable LED Drive Circuit




In this video series we implement an adjustable LED Drive circuit using the AL8862FF-7. In part 1 we review the target LED applications for our drive circuit and how the switch mode buck architecture of the AL8862FF-7 LED drive IC works. We then look at the schematic design for our circuit. In part 2 we look at a demo of our LED Drive Circuit in action. We also take a look at the PCB layout of the LED Drive Circuit. At the end we look at measurement data from our circuit including the max and adjusted current values as well as look at measurements to calculate the efficiency of the design. The extended Patreon version of the video include more measurement data on the design and reviews the ESP32 Arduino code used in the demo.
