This is the best tutorial I've heard on buck converters, I actually understand now.
Thank you, I subscribed.
It's also very nicely explained by Adamant IT.
Its 2023 and this circuit will help me on my thesis, ty Electronoobs, I will credit you in the references.
I love the way in which you break things down. Imparts knowledge in stead of just information... and extremely helpful for someone like myself who's trying to learn electronics.
Great video editing. You're very good at explaining things in a clear, concise manner that isn't too technical, yet still informative.
Why you only have 50k subs is a mystery to me. I randomly found your website while searching for info on buck converters, and you gained me as a sub with just one video. Keep up the good work, buddy!
oh. Thank you very much!
I never understood how buck converters work until now. Thank you for a great and simply presented tutorial
This is one of the best explanations of a buck converter that I've seen. Simple and to the point.
i used to say to others, their videos are the best in explaining, now i found new best explain-er videos :P really cool, helps all beginners, even pros new to the application topic. thanks!!!
I've watched a bunch of videos to get a grasp of this concept. Yours did the trick Thank you sir!
Very nice explaination. Imho your best Video so far - you're getting better and better.
At last...one feels illuminated. This is a much better way to explain the idea. Thanks sir.
Interesting and well thought out video, as usual, with very informative and useful content.
Thank you!
Your video quality is outstanding! Great videos, keep up the good work :)
Excellent description. Very clear diagrams that help clarify the concepts. Thank you.
Very great expainations about circuits and high understanable.Especially, that you explain, why is every part where it is an what does it do there.
Glad to learn from you.
Thx
and greatings from Germany!!
One of the Best video till date about buck converters
Wow! This is such a great video! Informative and so easy to follow!!
How did you calculate the inductor and capacitor values. Also, what factors did you take into consideration while calculating those values? Finally, how did you select the switching frequency to turn on and off the Mosfet?
Unbelievably high quality content.
Nicely illustrated!
When is the best time to use an optocoupler for feedback? How do you get around frequency limitations for high frequency optocouplers?
Your interpretation is very clear. I have a mechanical background. But I always like to learn some in power electronics !
I wish the best to you. This was beyond helpful
@Electronoobs can you make a tutorial of calculating the parameter of the component of each of the converter? that should help me a lot
Best video on Buck Converters
Really, really nice work, man!
You rock my world, I finally understand stuff thanks to you!
Wow! So clear and concise explanation!!! Thank you!
Thanks for the best-detailed tutorial. Is it ok if I use one of the simple voltage regulator to take 5V to 3.7V?
Thank you very much, your video is super well taught and finally I understood how these circuit work!
What about making your own very high voltage (100v+ dc) boost converter, You just adjust the voltage divider to suit the IC and get a larger inductor and higher rated capacitor?
The best explanation I have ever seen
You're a great teacher!! Very clear :D
Thank you!
Great video, super advice on technical aspects. What PWM frequency did you use on your own switching circuit? I couldn't read your scope you were moving so quickly :)
Great video. Excellent explanation. Congratulations !
does the voltage and the specs of the MosFet are important or can you choose a random MosFet ? Thank you
Excellent explanation.
WOW! What an awesome tutorial!!!! Thanks man!!!
Excellent lecture and demo . Thank you .
Thanks we can learn many things. I have a question is the Arduino ground and the buck converter circuit ground connect together or separate?
Waiting for your ans
Best video on whole Internet.
Very informative and easy to understand, thank you
I really appreciate your video. So many idiots on the internet explaining buck converters and feedbacks in such a confusing way. Yes you can just buy the LMxxxx, but I love the way you explain the DIY version, so that using an LMxxxx is just another step up.
Very nice.
Awesome job. Keep up the great videos.
Whoa, top notch video editing on this! Your channel is really picking up. I was already subbed, but this video made me turn on that bell!
Thank you very much!
Great video. Pleade tell me which mosfet i can use to built a buck converter 50v to 120v dc input with 12 v dc fixed output, load is max 1 amp
As usually good and very solid lecture.
I did! I did learn something! - Another Mechanical Engineer stopping by!
Great explanation!! Really nice video. Like it!!
Wow... Your explanation is so good! Exceptional... I'm learning about power supplies for Nixie tubes and your information is invaluable. I only wonder about safety of for example a NE555 based PS. Dedicated IC's have protection circuitry but I read that the often used Maxim 1771 has a poor design because the gate of the Mosfet is pulled to ground by a resistor: quote "a substantiol amount of power is wasted in the FET" But I need to look into that much more... I want a safe PS so I can leave a home made HV PS safely on 24/7.
Very good explanation. Thanks for your video.
Hi, a schottky diode is used because it is a high speed switching diode, compared with a 1N4001 series diode.
High speed because of the switching speed of the converter output.
very nice, very clear, thank you
Excellent!!!!! Liked to know how to change a 40vdc battery trimmer to a wired one. 110vac. A boost switch? How it works?
*BEST INTRO EVER* love IT !
Thanks a lot for better explanation of working of buck converter.
Simply AMAZING!
hi I love your video can you please tell me how you make that cartoon animation and which software do you use for that
great explanation
Very helpful, Thanks for sharing.
One of best explonations 😁 thank you 😁👍
You are the best ! Great video thanks bro :)
Hi
I the video where you explain the feedback a P-channel mosfet is shown.
But should the source not be connected to the input? Otherwise the body diode of the FET will make it conduct always.
Awesome tutorial
What is the current of the input voltage to power on a buck converter? Is +32V, 720mA DC or +16V, 610mA DC will work as my input voltage to power on a buck converter?
Can you please make a voltage booster circuit using IC 555 to charge 450V capacitor bank .
superb explanation
Best explanation👌🏻👌🏻
Great video as always. 👍 how to add current limiting to it and also short circuit protection.
Thank you for this explanation , but i wonder if the input voltage 20 volt what is the value of inductor and capacitor will be ? could you help me
He says check out the web site.
Okay,for N-MOS in Buck converter,i didn;t see any bootstrap circuit for High side switching
Nice explains thank you sir
amazing explanation
This has been very informative, thank you for producing such great content. Is there anyway to calculate what resistor you would need if you didn't want to use a pot? Ex. 12v DC input, limited to 7.5v DC output?
Ohms Law
Very well explained👍👌
Thank you💖💞💓
Can I drive the LM2576 switch with PWM from an Arduino instead of using a resistor/potentiometer?
Couldn't you use a OpAmp for the gate of the MOSFET..? To Regulate the output or charging of the capacitor based on the resistance or discharging of the capacitor?
how do i get a 15amp from this buck conveter? please reply.
Wow, thanks a lot . That's super cool
Superb!! Thanks
Can you please tell me what was the inductor you have specifically used in that project?
Hi. very nice video. But how can i make a 15 amp buck converter that can handle 60 volts. It seems when the voltage gets too hight the gate / source voltage gets too big this way? And how can I supply the arduino with power from same source we try to buck down? Als these tutorails make it look so simple but somehow it never fit my needs. For my solar shed and e-moped batteries I need 40 and 54 volt projects.
Thank you verry much dude you're the best ♥
Best satisfied chanel❤
How much resistive potentiometer did u use on the 9:29 circuit?
Dude just too good
Great video .. just I have one question why you have use transistor instant of connecting MOSFET directly to arduino??
The current from drain to source is affected by the gate to source voltage. The arduino can only apply 5V. To apply higher voltage I use a NPN connected to Vdd. Keep up!
excellent video
Thanks a lot for this great tutorial. 🔴 In my project, I use a solar panel to charge a 6V battery that supplies 4 outputs: 3.3~5V 0.12mA, 3.6~6V 0.12A, 4.8V 0.27A, & 3.4~4V 0.5A. Now, should I use the Buck converter for each single output? Is the Buck converter best choice for my project?
Very much subject to the dropout voltage of the buck converter especially when the battery voltage falls down. The multiple output requirements usually entails the use of a tapped inductor or transformer to avoid intermodulation problems between multiple buck converter regulators operating on a common supply.
11:10 Can we add supercapacitor "tank" (like 500 F) at the end terminals to smooth the ripples?
Thanks for the video .The problem with the lm2576 ic is the max 3A current . It will be great if you can make it higher. Say like 10A or more. I dont know if it's possible if it is please let me know.
Yes. So weird I never seen a real buck. Like 50A 60v.
Something is not right here.
I used pwm to drive this buck like he did but there is no info on how to connect feedback.
Well I got over 1000W on output. But I can't change load due to no feedback.
Good tutorial thanks.
Sir but you are having the ADJ version of the LM2576 IC and not the HV-ADJ version
So how can you apply 55 volts according to the schematic??
Good video, well explained. Maybe a brief explanation of the application of the fet and bjt would complete an otherwise very informative tutorial.
really good video
What ic should be used for upto 15 amp of current like lm2576 for 3 amp.
hi do you know if the lm2576t is the same as the LM2596T ?
nice 👍 explanation
Hi, your Arduino in the circuit diagram at 8:28 is not powered (GND not connected). Could you please explain how did you do that other than connect the USB? Thank you. Nice video overall.
Yes Yes yes videos like this we need take a hug like from your old friend "(me)"
