Very clear and simple explanation, thank you!

i am trying to calculate R1,R2,R3 for 11.7 and 12.7 . i can't figure it out

Where we can download that simulation?

Hello. If Im right I see you set BW limit (1M). But if BW limit is turned off sqare wayforms have spikes (in my case ringing) at the end of rising or falling edges. Is it normal for synchronus DC DC buck converter? My RT6222 (Richtek) IC has more than 150 mV out put riples @ 5V 1A / 3.3v 1.5 A with 13V input. I can't understand what problem is. Im using layout exactly as perfomed in datasheet. I know about all layout restrictions for hi freq DC DC.

I'm guessing the first one would be alright for an op amp, because an op amps have very low supply current am I correct?

Excellent video, I have a question, you have technical information if there is any to design a DC DC converter with positive variable input and that has a DUAL symmetrical output (high power approx. 2A) of +15 VDC and -15 VDC. Know of some base design with the theoretical source and some switching regulator.

Excellent. The best by far

Excellent. Thank you Gentle man. All these channel contents are the best ❤

Thanks for the great video! I have a question: Is there a way to dimm it via a pwm signal like from a arduino?

I'm looking to do this to measure ~ 150 VDC battery pack voltage in my electric car with a 3.3 volt Arduino board. Can this chip or another in the family handle such a high voltage on the input side, or should I use a resistor divider before the input?

I didn't understand one thing in the last method: why do we need an RC circuit for Pout and Pin? We could have taken 3 behavioral sources one for for V(IN)*I(IN) and V(Vout)*I(out) and last one for Pout/Pin.

the good old Steinel HotAir Gun....lol

What is the simulation algorithm type and integration type you're running? I ask, because sometimes I get convergence problems if I touch any (But not all) initial conditions.

It worked but very poor efficiency. But this video give me a very valuable knowledge. Thank you a lot. Hope you stay well since last video was 1 year ago. I hope you can keep it up.

Is it cv cc?

Great overview!

Thank you now I understand best how solve application

a stupid question: i'm using lt8302 for a dc-dc converter. i've set up everything but when i start it up, the lt8302 doesn't switch. there is permanently di input voltage at the switch. how can i make it switch on and off ? that was the case in the simulation but i used the command .tran startup and it worked. what should i do now in reality?

Excellent summary!

Nice, but I have one doubt, consider my Iout is 2A, what will be the current before the inductor, whether it is greater or lesser or equal to output current, can you say with any example, it will be very helpful

Great video, thanks! Would be great if you did an isolated flyback (or whatever topology) that includes a TL431 and opto.

👍

Thanks, it’s a great walkthrough. Please provide us more buck and ldo testing like this one.

Thanks a bunch for this information. I only wish I had this explanation while I was going through classes lol.

Hello, i am trying to do the exact same thing(DC-DC BUCK converter), but im using a 9v battery, How do you propose i go about this. Note that this will be done on a bread board as well, can you give me an idea? Thanks.

Very useful, thankyou very much man ❤

great knowledge about the ltspice transformer simulation. can ltspice simulate an Analog Devices AD202KN transformer transformer with the opAmp all prepackage 🧐 thanks.

Hi, are the initial conditions applicable only for DC output values? Suppose that I am simulating an AC output waveform and if I want to provide an initial condition of RMS values of output voltages..how to right spice directive?

Hope you attach your files used in the demonstration it helps ,thanks for your effort any way, appreciate

Cool! Very informative! Your video editing is great!

Concise and comprehensive. Thanks!

There is also another method, using .meas commands, then "Ctrl+L", specially useful for stepped simulations.

I have used LT3763 but I don't solder the exposure pad as you, then my product wasn't working, when I put the load into the circuit, Vss (voltage soft-start decrease to 0V) and I put the load out the circuit, Vss increase 3.3V. So I want to ask you: " Is it necessary to solder the exposure pad? I'm looking forward to your reply? Thanks you.

This was amazing... Thanks for sharing boss.

Hello Thank you so much for this helpful video. can you please tell me how can I model the third winding (1-2)?.

just a quick dumb question...why would you isolate a DC voltage ?

Thanks for the video. I'm a complete beginner in LTspice.

The heatgun-from-below technique is such a nice way to do reflow soldering. Much cheaper than getting a hotplate and faster too.

Very good and understandable explained ! If you want to make a lab power supply then you also have to introduce a op amp for current sensing does that mean that you have then two different compensations which adjust the feedback line ?

Woww Woww woww!! a New geeky channel to watch out for!! damn nice!! as a bachelor grad doing work on supercap model as well as PCB this is one of my favourite crossover.. would love a follow up on design of this system using Altium/Kicad design for this circuitary and more supercap application!! Kudos for this amazing content!!

Great video. Thank you

This technique is good , but not the best option

Tq..you got a sub

Nice video. Well put.

May I get your email? I want to ask some questions. Thx

Thanks for making this. Question: In your simulation it looked like there was about a 0.5ms response delay between input voltage and output current change. That seems quite long. Is this correct?

Awesome.

Very well done and well explained video!

share the schematics

Nice one again.
