Jellybean components videos, not yet made
« on: July 20, 2023, 09:25:35 pm »
The Top 5 Jellybean component series is quite nice from David Jones. I am surprised that there is not yet any video on the top 5 Jellybean component videos on the topic of:

1. SMPS
2. ADC
3. DAC
4. Voltage converter/translator IC
5. Microphones
6. Speakers
7. Displays e.g TFT, LCD e.t.c.

I think that there should atleast be video on switched mode power supplies but have only found one on linear power supplies so far.

I really wish that there would atleast be top 5 jellybean ADC and DAC video, mankind really needs it at this stage of evolution.

There could be an ongoing jellybean series looking at as many jellybeans as possible. I too would be interested in watching this.

SMPS is as important as the linear types. I really wish that video was already created.

I'm keen again!
Comments on previous videos seem to have BJT/MOSFET's as the next most popular one to do?

I just found the EEVblog 1599 - TOP 5 Jellybean Bipolar Transistors.

Nice.

Looking forward to other transistor types and SMPS.

Thanks.

I'm pretty sure there's only 3 categories of jellybean switching power supplies - wall warts, ATX PC PSUs, and screw terminal modules. (The last one only being a jellybean due to their common use in 3D printers.) Everything else is proprietary and customized for a specific application.
Cryptocurrency has taught me to love math and at the same time be baffled by it.

Cryptocurrency lesson 0: Altcoins and Bitcoin are not the same thing.

Yeah, I can't see how I could make a video on that one.

SMPS controller IC is what I meant.

Do diodes, small signal and medium current (1amp, 4amp).  There are a few classics which everyone should have lying around...

Like 1N914/1N4148.
Like 1N400x series 1amp silicon diodes.
As well as BAT54/A/C/S Schottky barrier diode, the serial dual ones in SOT23 case mainly used for protecting MCU/Comparator/Op-amp input pins from over voltage and static voltage spikes.

Maybe include a zener or 2, though, these guys will be more specific to the voltage one needs.

There are a couple of classic, but I don't think they are really something people stock and use "jellybean" though. I'm not feeling it.

Some ultra low cost stuff still use the MC34063. As if it wasn't cheap, it seems it could be done cheaper.

ttps://www.htckorea.co.kr/english/sub02.php#link9

Or the other ones might be reselling those.

This might be the most jelly been SMPS IC around.  €10 cent 2.5K quantity with no competitors for what the IC offers namely the high input voltage range. But, a modern 40 cent IC might be lower in costs if you also look at the cost of the surrounding components because the MC34 requires a large inductors and ditto capacitors eating away your board space.

What's the real costs of low cost old timers?

For off-line switchers the UC38xx series are still popular.

Most anything offline SMPS isn't really something you'd want in a YT vid, or advertising as jellybean.  UC3842 etc. are fine at low voltages, which should be plenty as a learning experience, and practical already, without getting into the safety and EMC issues an offline SMPS has.

The real trouble with offline controllers/regulators is there aren't many jellybeans as such; there are dozens of cheap and generic ones, particularly Chinese (Taiwan or otherwise), that don't show up on western distributors, don't even have English datasheets, or perhaps even aren't generally available if you aren't in walking distance from the factory, give or take NDAs, etc..  So, it's the kind of business generally left to few highly-interested, specialized, or otherwise privileged manufacturers, and, with the other issues of those supplies, that's kind of just as well.

Speaking of 34063, perhaps a video explaining why they're so awful, and why the alternatives are so much better -- at least NCP3063 for example, or NCV5173, but also the myriad other easy-to-use regulators, and how to choose them; the proper answer these days is not to rely on any single part that's poorly suited to any particular application, but to understand what they do and how to select one for a given application.

This is IMO why this topic doesn't make for a good a jellybean video.

Super idea Brian   :-+

However...
...Like 1N400x series 1amp silicon diodes...
Yes! But, then Dave can explain to his followers why the slow, noisy, pieces of shit, should never be kept in stock, at least not to be used as a rectifier.
