I like Afrotechmods narration feels like watching documentaries not lectures :-)

The best person often does not get the best views or hearers. I got an engineering degree but all electrical old stuff not much electronic, your channel is the best of all. Electroboom is good but you are a great teacher.

+Texas Instruments Glad you liked it. Been using your products for years!

+Texas Instruments I have studied and gone to several lectures on this area, but this 10 minute videos summed it up really nicely :D Kudos +Afrotechmods... keep up the good work :)

+Texas Instruments i didnt expect that...

I wished Ti would have more reference designs for us newbies on their chips. I mean more reference on variable outputs using digital pots and linear pots would be nice. More references on pass power transistors for more current output too. I always throw together a lm317 circuit for 15 amps or more to test audio amplifiers. I could figure this out but would rather not blow out $200 worth of parts before I get close. And as far as I can see, none of their simple switchers, high amp series chips have any reference for soft start circuits. What's the first thing a newbie going to build? A high amp variable voltage power supply . Make it easier for them and get them hooked on your products and they'll use them for life at what ever company they're working for....

It's sad that none of you guys will do a tutorial video on how to solve feedback loops for compensation networks in switch mode power supplies. You guys always take the easy way out with using devices that have the compensation networks in place. Is it really that hard for people to understand it or is the math too advance that you might scare away people?

lol same

Arnold sure loves killing things.

honestly I almost fell off laughing when Arnold interrupted...lololol big thumbs up

And a suitable slope comp- SHUT UPPPPP! Really Arnold, you are a buzzkill.

What...?

@@aheckers Basically everyone was saying, You're a buzzkill.............STOP BEING A BUZZKILL

Not expected to see you here :D

Oooo u r real ....

Glad you like them!

Omg thank you!! That means so much to me coming from you!

Afrotechmods Thanks! It's great to see you back on youtube.

my two favorite utuebs in one place. circle of smarts

oste19 Glad you liked it! He'll be back.

In my neighborhood. They are everywhere and pretty cheap.

Yea but how long do they last and how reliable are they, and will i have to hide my valuables

Yup. They'll pawn your Fluke multimeter for $20.

LOL Crack-heads, real life zombies!

Lmao!

Thanks! There have been a few uploads this year. Check them out!

Same. If you have found the magic search terms for this, I'd appreciate the info.

You'll be back.

You have won the internet for today. Both with the awesome video and the superb referencing comment.

Don't discount linear regulators too quickly! They have their niche too. Without the switching action of a SMPS, they generally have cleaner outputs. They also don't require inductors, which is very important because inductors are by necessity large and expensive(in a relative sense.) With a low dropout linear regulator, one could achieve reasonable efficiencies by keeping the input to output voltage ratio close, though care must be taken not to come too close to the dropout point. As afrotechmods mentioned, in the range of about an amp or lower one could consider using an LDO, and the total solution size, cost, and output ripple would be superior to any switching power supply.

I was pretty impressed that I pulled it off on perfboard too! The huge ceramic caps I used were larger than you would ever need in a commercial design, but they give extra leeway for beginners to make mistakes and still have good performance.

Afrotechmods Will the efficiency be higher if I solder the components directly to each other?
