what can I say, I suggest adding two buttons to submit the saved code, one to select the code and another to submit, or just one button to do everything. I mean short press to select the code and long press to submit

​@@MyVanitarso thanks for you ❤ Please give to me void code for transmitter sending code is older saved! Please help me Thank you

​It is very important for me to select and send this function of sending old saved codes with two push buttons. Thank you for your help

@@eerrfanshayyestehh2069 this is a task that you should follow and experience personally, brother. I have no time to modify the schematic, PCB, and code.

thank you ; For taking the time to answer me, dear engineer; I wish you success🙏🙏

to download my projects, you don't need to buy a license. just register on the website using the link in the video description/article. I upload the projects files in the Altium-365 cloud space

Thanks let me check

The first try takes time, after that it's a piece of cake

Glad you liked it!

simulation is something else, this is for schematic and PCB layout

Thank you very much. I hope others also follow you

Thanks so much

Yes, why not. this is a very low noise supply

@@MyVanitar thanks, sound quality more better since i use this power supply

@@hemamadni2117 glad to hear that

how much is the inductance of the primary in your transformer?

how much is the inductance of the primary in your transformer?

@@MyVanitar Sir, inductance as: Lp = (4-5) 2.50mH / ± 5% and it is PC40 Core

@@thanhcong9278 compare this with my calculations. if the primary value is close enough, the secondary winding affects the output voltage and current. I suggest you wind it yourself if you want to learn

@@MyVanitar Yes. Thank you for your help!

These chips are all protected against short circuit

@@MyVanitar Not true. Look at the schematic. When output voltage is lower than input (short circuit condition) there is direct current path through inductor and diode. It should have at least a fuse on input power line to avoid major disaster.

it depends on your input supply. also when the input drops below 5V, the chip turns off. Maybe the EN pin can also help, but for my case and purpose of this circuit, disaster never gonna happen

usually, a boost converter is more noisy than a buck. check my latest video. although the current is low, it shows a square wave ripple. a 470uF input capacitor does not cause such an inrush

@@MyVanitar Well i guess that the inrush current depend on the ESR of the cap. What formula did you ude to calculate each components values like input and output cap, and inductance?

if you want other output voltages, simply change the feedback resistors. also, be careful about the voltage rating of the output capacitors

@@MyVanitar yes I understood.

Thank you Neil 🙂

Thank you! Cheers!

Most welcome

I am agree

go ahead and build it

for this project, the link is inside the article which I'll put the link to the article later on, however, from now on (whatever is published after this), the link to the Altium-365 project will be provided directly in the video description.

test it, it works :-)

you've made a mistake somewhere, I'm sure. check again (both video and the article).

@@MyVanitar ok thnx for the reply

@@MyVanitar I did every step as the vedio mentioned and I am getting the error pico/stdbio.h no such file or directory

how do you run the VSCode? from which command prompt?

@@MyVanitar it fianlly worked . thanks a lot .

I don't know, but a voltage glitch (on/off) probably caused this, because they calculate until their power is connected. to avoid this, you have to store the latest data on an EEPROM or something, every 1-2 minutes for example

nothing. it calculates based on the input voltage and current, however, I'm thinking about the capacitor-based supply for the chip (not the chip itself), that might cause issues if the voltage drops too low

I have another design as well, V2. check my videos you will find it

@@MyVanitar yes most of our meter lost stored energy on voltage drop areas , due to what reason happen or which electronic component causes

This is not the problem of the meter, it can be easily solved to handle even as low as 85V-AC

Bingo

Glad to hear that!

12V-4A means 48W. The maximum power of this Flyback chip is 24W. if you have a project request contact me via Email

@@MyVanitar i'm a college student and i wanted it for my for my project this semester, just having a trouble adjusting output voltage and current and controlling them separately . sadly i can't afford a project but i would really appreciate any tip you can provide .

I have a 12V-7A version on my channel. check the details for your info. The output of these supplies is not that much adjustable except you use a buck converter at the output

@@MyVanitar thanks .

the same as a technical class in the university?

Let me reply in English. Just follow the link in the description and activate your free legal license. if you did not upgrade, it doesn't matter, you can download projects from Altium-365. I'll put a link to the article later on where you can find the 365 link as well

I did not get what you meant, what's the problem with this layout?! when the copper is enough, it won't heat noticeably. open a channel and show your professional projects and do things properly!

​@@MyVanitar I was talking about PCB traces layout. Traces where you sense voltage drop on shunt resistors. I'll be happy to continue discussion after you have a look on some doc. Please search for AD's document optimize-high-current-sensing-accuracy.pdf and have a look. That's much more close look how to properly do tracing, while on your PCB it's far from proper approach. Do not get me wrong, I'm watching your channel not to make critics. I've just spot this and want to pay attention. Will be happy to continue discussion.

@@MyVanitar ​ I have to repeat a lost comment. I was talking about PCB traces layout. Traces where you sense voltage drop on shunt resistors. I'll be happy to continue discussion after you have a look on some doc. Please search for AD's document optimize-high-current-sensing-accuracy PDF and have a look.

The "maximum" power dissipation on the shunt is around 1.25W. the shunt is rated at 6W. can be increased to 8W. Resistors on the source pin of the Mosfet are rated at 12W and can be increased to 16W. maximum power dissipation on those 4 resistors 6W but they won't affect the current reading. This can be even improved if the value is decreased but the user would miss low current adjustments. Load ground and input ground are also common. current sensing is the high side method. if you mean the traces from the shunt to the chip, they are short and identical

​@@MyVanitar I'm sorry, but you are still wrong and/or do not understand what I mean. Did you found the pdf I mentioned? Read it please! Your math about shunts wattage does not eliminate the fact that traces for main current sensing shunt (R9 || R10) are placed in a way that violate well known, proper tracing. Those sensing traces literally should go under shunts and have to be connected to internal side of pads where they soldered. Not like you have right now on one side which we see, it's even on some distance from soldering pads!

Thank you 👍

@@MyVanitar 🙋‍♂️🙋‍♂️👍👍👍

Thank you. I will provide the article link as soon as it gets published. by the way, watch the video completely till I put that link because you get values from both.

@@MyVanitar Thankyou for the reply, sure watched it fully , thankyou for your wonderful explanation of the design as well in the video .

My pleasure 😊

Not a screw, but a plastic washer

@@MyVanitar I meant a nylon bolt. If you use a metal bolt and a plastic washer it could still short out

whatever I say you make your assertion :-), no problem, use that bolt in your designs

please do not comment without watching the video!

@@MyVanitarDon’t be a jerk. I watched the video and that’s why I gave advice based on my experience. All the manual work of installing everything individually has been replaced by one click installer. What was wrong with my comment?

man, the first step of this tutorial is about installing that package, but that package is out of date, that's why we should update some parts. Please watch the video completely and be polite, I don't owe anyone!

I will put the article soon in the description, then you can read more and see the specs

Thank you! Cheers!

unfortunately, I'm not from India and I don't know Hindi

@@MyVanitar So , I would like to suggest that you should learn Hindi.

No, maximum 90V-DC

@@MyVanitar any buck converter support 200 v dc?

I can design it for you as a premium project. also, I have some designs that can get 230V mains input on the channel, but the output is fixed

Thank you! Cheers!

I saw your Email and replied. yes, it's possible

Thank you :-)

You're welcome 😊
