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.

How to Design a 24VAC to DC Power Supply for HVAC Applications Part 1

 In the video we look at how to design a 24VAC power supply for industrial and HVAC applications. The supply will be flexible enough to handle DC voltage inputs. The power supply will employ a DC to DC buck converter, half wave rectifier, input protection against over voltage, and output noise reduction circuit features
