![]() The task is to design a standalone DC-DC buck converter PCB layout. ![]() Buck Converter PCB Power Supply Requirements ![]() You’ll also find all the components used in this design in my extensive open-source Celestial Altium Designer Library. As this design has been completed by someone else, the schematic style is a little different from my usual projects. You can find the final PCB design for this project on my GitHub page it’s released under the open-source MIT license. I thought it would be more interesting to hire a freshly graduated electronics engineer without much experience in power supply design and have him design a power supply with just the requirements listed in the student project ideas article. They seem trivial on the surface - add a few caps, IC, inductor, and a few resistors, right? The current loops on a switched-mode power supply and component selection, however, are non-trivial. I figured that since I’ve designed hundreds of switched-mode power supplies, just running through design is probably not going to be perhaps as educational or informative as it could be on the pitfalls or issues associated with designing a power supply. In this article, we’re going to look at the implementation of one of the power supplies in that project. I suggested working on projects that would help cement their skills as well as show their experience with design - I wrote an article with suggestions on getting started on projects and some project ideas. After my Reddit AMA with Altium, there were a lot of questions from students and graduates asking what they could do to improve their skills and show they are worth hiring.
