This LinkedIn discussion generated a lot of interest and even the experts couldn’t agree on whether there should be a ground plane under the switch node and whether copper planes should be placed under the output filter inductor.
We designed 4 variants of a simple, open loop DC/DC converter module to compare the results of these changes. We made this an open source project, so you can make your own board from our FREE Gerber Files and BOM (see zip file below), purchase a finished board set for your own experiments or modify the design for your own needs.
Some are interested in thermal aspects, some noise, efficiency and many EMI. Whatever your interest, the data should be posted here so all that are interested can see the available results or post their own.
