Design Review with Dan and Kirsch - Flyback Converter

In this video, Kirsch Mackey sits down with Dan Beeker for a detailed review of a real PCB design, examining both the schematic and the layout. As they walk through a four-layer flyback design, they explore ground strategy, isolated domains, return paths, and via usage. This is not a surface-level layout critique. It is a practical, technically grounded discussion about managing energy in three dimensions, understanding transmission line behavior, and making layout decisions that reduce EMI, improve efficiency, and strengthen system robustness. If you design mixed-signal, power, Ethernet, USB, or other high-speed boards, this review will likely challenge some assumptions and reinforce others. The goal is not just to fix one PCB, but to help you think differently about how fields, planes, and components interact inside every design.
