Thank you! Like @Mai Mariarti mentioned, I know understand why I've destroyed so many of the ubiquitous MT3608 boost converters... Still catching up with the videos and re-watching many, thanks for the effort you put into them.
Great video again! You should test one of those very cheap little boost converters from ebay china without a UVLO. They are crap but the output voltage can spike up suddenly to values not expected and much over specs - so you have to watch out where you can use them (if you want to use them at all). If you power them via battery or solar generators you will get into situations where the input voltage will slowly decrease and this can kill your load - e.g. when you use them to power led lights etc. I didn't get them to blow up the output caps so far - probably because the spikes are not too powerful or i cleared the situation too fast.
Thanks for the great question! Input capacitors will cause a large inrush current even before a power supply starts to work. Here's one of a number of videos that I have done on inrush current, but I will have more to come;) th-cam.com/video/gmIXSfQRBhA/w-d-xo.html
Wow at 7:36 ish, it looked like the inrush lasted for a couple seconds there! I'm used to current inrush only lasting microseconda, but i haven't tested power boards. Is the "long" duration due to the large amount of input capacitance?
Great video! You just kill it this time:-) Floating, "no editing" great angles and yes, just well made! :-) Super smart with ULVO! A question ULVO, is that not rarely used? I mean, when designing and specifying, do you not try to avoid coming anywhere near ULVO's window? Even I wrote about Fluke being more saleable for hard usage and Electricians, due to it's lower resolution. Do I think that a solid meter like that is perfect when working with designing of a power supply! You have to use a meter you know, can handle the main side and do not blow up in your hand! When you are on the "safe" side of the transformer, can you always use a cheap meter, but not where it can get dangerous! :-)

Thanks - I appreciate you!
Thanks for the video Eddie! Haircut is looking good!
Thanks Jared - it does feel better. It is getting hot here in Utah.
4k subscribers! Way to go!
Thank you!
Another great demonstration..
Thank you!

Thanks for this feedback! I’ll have to review more of these and run them thru the paces.
Out of curiosity, what's causing that huge inrush of current right before it turns on?

Thank you - much appreciated! I’m trying to follow your advice;)
@@KissAnalog LOL then I hope my advice is not only my opinion alone:-)
