I spent hours trying to get my head around buck converters the other night and now you've explained it completely in five and a half minutes. Great job, thanks!
+Carl Alm Thanks for the compliment ;-)
+GreatScott! can you make a tutorial for DIY FLYBACK control by PWM? please
+Carl Alm Yeah same happened with me. I had my project ready but i accidently used adjustable version with no feedback so jumped back to 7805. Now i understood my mistake. Great work +GreatScott!
@@miguelfierrospena6758 It's basically the same, but they are current controlled. That's good because they do limit current well.
the simple way to think about it is that, at high frequencies, the average voltage on one side of an inductor will equal the steady voltage on the other side.
Fast, efficient commentary, nice use of oscilloscope to demonstrate effect of each component and components used named and specified. Beautifully done! Couldn't be better.
I love your ways and methods of teaching. Wish I had a professor like you during my Electronic Engineering days. Short Crisp and well edited videos. Full of information and practical know how... Thank for sharing your knowledge...
I didn't know much about electronic, but now I have watch your videos in about 5 months and I learned something. Thank you Scott for making TH-cam a better place (:
I got interested in electronics due to your videos!! Thank you so much! I'm now building an automated robotic arm! :)
You should build a electric car! :D
Merci. Now you're even GreaterScott because of the French subtitles... Thanks to you and to whoever devoted to do it. It's just perfect.
I love these theory videos that explain a concept. You're incredibly good at it. You're like the hobbyist version of the "The Great Explainer" Richard Feynman.
I saw this video a couple weeks ago while learning more about electronics while knowing Basics. I understood parts of the video but a lot I didn't. After going through many more of your videos and other peoples videos I came back to this and understood it perfectly. So if you were like me and did not understand everything from this one video, don't worry and just go look through more of his videos and other video that explain other electronic component uses and some theory and come back after a while and you will understand a lot better. So thanks for the education GreatScott!
Definitely the best explanation of how the various parts contribute to the buck converter, that I've ever heard.
Great video! One of your best yet. haven't found many short and to-the-point DIY buck converter videos on TH-cam. They're usually split into 5 parts and never get around to building the circuit.
didn't understand inductors fully in my education, but with the scope waveforms everything is crystal clear, now kinda like inductors amazing component, best explained ever.
Fantastic video - thanks a ton !! Love your quick paced; well thought-out content approach; and perfectly edited style !!
Great explanation, I really like how you added one component at a time then explained why you added it and what it does to the circuit, most tutorials I've found don't really go into detail on why you need an inductor or a high switching frequency as an example, Thanks.
+vgamesx1 yea defintiely very well structured videos!
I have legit learned soo much from watching your videos over the years , I had no idea I was learning as much as I was , until I found my self predicting the next components you where gonna use ... I have no formal education on electronics , just TH-cam and tinkering my self
I see you doing these things and it sparks my interest in studying this field. It seems to be great and fun to Learn how electricity works
May I say thank you for your wonderful video. I don't know much about oscilloscopes but may God keep giving you the tools you need to be able to teach us. Thank you very much
What happened to "Let's get started"?!
Lol
+barnstormer322 I tougth the same!
+barnstormer322 I like it more than "lets figure it out!"
yeah, bit less of a mouthful :L
barnstormer322 And sounds better with his accent
GS..I used to know IC chip names by Heart and By the Family...watching your channel has brought back the inner geek in me.
Ofcourse I go searching for a good video to diy and it's a great scott video as usual. Keep up the good work and helping the world with knowledge
thanks for the oscilloscope portion , it was helpful to see why we need better regulation for sensitive projects
the terminator is also an electronics wizard! who knew!!!... great job keep it up
Very nice buck SMPS tutorial. Short and clear. Right on point.
250000 SUBSCRIBERS!!!! congratulations!!!!! great(scott) work!
It is a very good video, very useful with great explanation. Keep up this quality and I can't wait to see your upcoming episodes.
Cool, this is the first time I really understood how switch mode PSUs work. Keep up the Great Work :)
Uber explanation!! short and precise with scope showing signals! Thanks "GreatScott".
That's a REALLY sexy scope
edit : also REALLY expensive, that's a solid 6 months of rent xD
+BillTheBox He got it for free :/
Eddy Fuchs HE DID ? WHERE ARE THESE MAGICAL PLACES WHERE YOU GET FREE 5000€ SCOPES ???
I don't even own a fucking working dishwasher and i'm busy drooling over these expensive things :o
BillTheBox
Yep, Keysight got a generous giveaway month recently, one scope every day, one super scope every week and one super scope for many youtubers
Eddy Fuchs when and where did this happen ?
BillTheBox
In our known Universe in the Milkyway in our known sunsystem on earth (you're not dreaming) and I think it was this March
amazing and beyond my comprehension at around 4:25. Awesome video. I am just a beginner so it is good that I stayed with it for that long.
That was beautiful. Inspiring. To the point. Thankyou!
Your handwriting is awesome
I know I'll find an answer when I'm searching a subject & I see a GreatScott video in the results!
when I first started watching your videos I could barely understand anything............but now I see a huge improvement in my understanding of electronics........ thanks man!!
+Sumit Aggarwal Awesome
+Sumit Aggarwal I agree! Great video! Thx GreatScott!
To novices who are scared of Switched-mode your explanation made things really clear and easy to understand.
THAT IS AN AMAZING OSCILOSCOPE!! ♥
Awesome video, like always. Greetings from COlombia! :D
This was the tutorial I needed, thank-you!
Great insight into buck converters. Well done !!
I really enjoyed the way you stepped us through the development of the circuit - very well done. Having checked out your other posts I can see I'll learn a lot here. Subs +1.
big fan of you and your way of work and let us learn. thumbs up
Amazing explanation, You are Great Scottt!
Awesome video man, keep up the good work! :)
I use LM317 it's been 3 year..
Very good regulator.
I didn't know about this LM2576. I'll try it.
Thank u.
I looove your accent, handwriting and brain.

Simply genuis thanks for all your videos yr friend from morocco
thanks sir Scott for this Amazingly Helpful videos
Greetings from tel aviv ,israel
I love your videos ,
keep up the good work .
you are just awesome man! just perfect. I am a student of electrical engineering in Pakistan (Asia). But unfortunately, we aren't being taught these things here. Just bookish crap. I wish I could work with you. I make small projects in my house. I love it. but I will die to learn all the knowledge you have got.....! love you sir!
Very cool! It's perfect for my solar-powerbank project!
Oh my god ! Thank you very much, this is so helpful, you have no idea !!! THANK YOU !
And keep it up! Love your content :)
Hi great scott! I am 14 years old and as usual it is again an awesome video. keep up the good work. GREETINGS FROM INDIA
Grate video Scott and Happy New Year
I always learn something from your videos, I just wish I would do 1/100 of what you can... I lack good solder skills and end up burning smaller parts rather than solder them... Cheers Mate, great Video as always....
Just supported the patreon, liked all videos and subbed
As always, great content. And love ur scope ;)
You are a master of movie editing!
You are a master of mustache editing!
Perfect. Exactly what I was after. I'm currently building my own LED strip light driver and controller. Got an esp32 for wifi and lots of pwm. Using some logic level mosfets in there for switching the 12v but I want to power the entire board from a single 12v DC jack. Need to add a buck converter onto the board.
Very good informative video.I use the MP1584EN SOP 8 in my designs which is half of the cost , which is a key factor when you are running production.Great channel.
Wow, that oscilloscope looks SUPER cool. I wish i could afford one of those for my silly projects.
Just what I needed it! thanks a lot!
Beautifully explained.
Such an excellent teacher, amazing videos
Thanks mate :-)
Thank you very much just what I needed :)
I used an arduino to open/close my car using my phone (new project in your channel??) but my problem was the power I did not want to use linear voltage regulator so I looked into the buck converter and they are awesome !!
thank you for your video it makes my sunday better.
I am AbdulRhman and I am from Saudi Arabia :)
I am so new to building in this fashion, but I personally wanted to say TY for being So Descript about parts used and thee list of parts and where to get them Again THX So Cool Man!Keep it up And Please Make More Videos!
GREAT TUTORIAL AND DEMO...... GOOD JOB.....
Thank you. Your videos are very helpful
"lets find it out" The things that get me excited haha
Great project and explanation!
damm!!! this man knows what he is doing ****thumbs up (y)
After watching this about 10 times I actually understand this properly
Fantastic presentation!
Hey I requested a buck converter video and you did one! Awesome video and thanks!
Really nice, think I'll use this in my next project instead of a 7805
Great video! And that's a nice scope
+GreatScott Awesome video as always, its definitely worth supporting you through patreon, thank you for all of the hard work you put in.Vielen Danke
awesome production.
Awesome video. I need to make one of those!
your videos are awesome
an step up converter will seem like the next video i will liked
I have no idea what he's talking about every video. But for some reason I still watch the videos xD
Please do a boost converter next! This was awesome!
Another great video! Like others, I would love to see a boost converter.
thanks! i needed it hahaha i was building an rc hand launch glider and the lipo was 7.4v, so i needed a 5v ubec.
As always. Good video.
Awesome explanation!!! Thanks a lot...
GREAT video Scott.......:-)
Well done. Now I better understand how buck converters work.
Nice, the old intro. I like it.
hey Mr Scott
great video as always but
I might recommended that you would complete the arduino buck converter but although a very nice high quality project keep up the good work
I learned that ICs are really helpful by simplifying your circuits lol
Very informative. Thank you!
fantastic... as always...👍
please please please boost Coverter next!
Dude you do a great job of breaking these things down, explaining them. Would/could you consider doing a vid on self excited generator. Think you’d find it interesting. Thanks again
I would be unable to understand all subtitles by myself thanks so much ! 😎
Great, simple explanation (this guy is way smart), thanks! (And saved me @ 2:15 from destroying my SENSIBLE electronics. LOL.)
Excellent video !!!!!!!!!
Your videos are always good, I notice most of the time Europeans are more intelligent. On many American videos I notice many things repeated that are not correct and many people doing things wrong. Most of the time when I find a European doing it they clearly have an understanding of what they are doing and add no nonsense.
Very informative video.
Thanks! It helped a lot :D
Gratz on that killer oscilloscope! I already miss the Rigol... but who can argue against a $13000 piece of equipment :)
Hi. I thought you had already made a video about it, but I think it was Afrotechmods. Anyway, well explained. regards
