I just updated the wrong footprint and corrected the PCB gerbers. The updated project files are available and can be ordered from PCBWay's "shared projects" page: www.pcbway.com/project/shareproject/Miniaturized_Buck_Converter_46919872.html All information should be available including a BOM as .csv Also: I'm not to be held responsible for any design or functional issues.
Fantastic video! A good thing for smaller projects. I would love to see a video about a custom CB radio frequency transmitter, for digital serial data over a long range. (Nrf24 does not work great at a longer range) So I think a longer wavelength would prove very useful for a "digital walkie talkie" kind of project. Hope you will try it ! Good luck 🤞
Thanks! I'm glad you liked the video. It's a great suggestion, although it would appear that the only thing I have bad luck with more than component footprints is RF projects. I've been trying multiple ones over the years and have basically failed at all of them... If I ever get anything working I'm most definitely making a video about it!
@@5VLogicBetter to try on a breadboard with an LC circuit or a crystal oscillator... Or first try with FM radio frequency to test the transmitter first before making the receiver. Troubleshooting is a must 👍
Not yet, but it's an idea. I should look into doing that. I'm a little doubtful on how many people would be interested since it would require people to also order the components. EDIT: just got it done for the small version. The large one I'm tempted to avoid. Maybe I'll do it some other time.
Of course, it's an electronic load, I made a video about it maybe 2 years ago, it's quite useful when testing DC converters. Here's the link to the video if you're interested: ruclips.net/video/ySyOoFI5cqA/видео.htmlsi=qG8SAWzj0f9ea9Vo
I can't help but wonder if the noise and switching frequency aren't combining into a destructive waveform that reduces power output when you increase input voltage/amperage. 🤔🤔🤔
That's interesting, I'll check it out. It also occurred to me after I made it, that I could have used a controller IC with integrated MOSFET, this would make things even smaller.
@@5VLogicA switching solution with a higher switching frequency will dramatically reduce the inductor size - or at least volume if not footprint as much.
The two resistors at the output (Rfb1 & Rfb2) determine the output voltage. The voltage divider must produce 1.25V at nominal output voltage. Also: all components must be rated for this voltage. And the input must be higher than 24V because it's a step-down converter
You must be fun at parties. It's the process of research, design, build, fail, back to the drawing table and start all over again until you have what you want that makes it fun. And you can easily change things your €0.15 buck converter be able to do like support a higher amperage.
Making something helps you understand how it works for fault finding so you can repair a laptop motherboard for a few pence/cents rather then paying hundreds for a new motherboard. Education.

Thank you for sharing your experience and showing the trials and errors you encountered along the way.
@05:22 When the fuckin Shipping is like 314% the Price of the Manufacturing 🤣
Yes same with JLCPCB 10 PCBs for 2$ and shipping to the neighboring country India costs about 35$ 🤣🤣
Great work!

very interesting and entertaining video … looking forward for a @5VLogic vs @GreatScott! PCB competition 😂
Thanks! ; )
Have you created a kit on PCBWay that we can all buy to make our own one?

@@5VLogic do you have a link to it please?
@@retrocomputinggrotto Yup: www.pcbway.com/project/shareproject/Miniaturized_Buck_Converter_46919872.html
Thanks very cool video, could you please explain the device with the big cooler, was it an adjustable electronic load? Thank you

The background music (Lobby Time?) i think is used in the game Satisfactory, no?
Around 3:00 ksp music is on
MP9943 IC is also a good option I think. I have seen this on most of the Flight Controllers.
That's interesting, I'll check it out.

if i wont it at 24v what i need to replace ?

nasty pinless smd mosfets allways have the gate on the wrong side, its screwing me up every time i want to debug something
Wrong side? Its literally always on pin 4.
@@VEC7ORlt almost any TO, SOT part has gate on the left pin (1), SOP DPAK and DFN on the right (4)
its completely messed up for no reason
sure go ahead why not painstakingly make a thing that costs 15 cents
You clearly are not a man of culture. The joy is in the design my friend.
