A Noise-Free DIY Switching Power Supply - How Hard Can It Be? -- Episode 542

Switch Mode Power Supplies (SMPS) need a printed circuit board (PCB). To see why check out this video. We look at how hard could it be to get a PCB design right! Hint: You need copper zones to get a low-noise SMPS design.

  • Great episode. I got to it a year after releasing, but glad I found it.

    I guess one solution for less skilled HW designers might be that there will be ready made modules that would be connected to a target PCB via castellated edges or just pin headers, just like use processing power (e.g. Raspberry Pi Pico) / communication modules (many GSM / BT / GPS modules).
