This is a great tutorial man. Thank you sooooooo much!!!!
Glad you liked it!
Thanks for the tutorial. I have some questions to ask: how does it work as LM358 in the stimulation part because we only create the block diagram and footprint?
simulation is something else, this is for schematic and PCB layout
Thanks
Thank you very much. I hope others also follow you
Hi my friend; all your products is the best Good luck
Thanks so much
Can i use this for my audio amplifier (STK4221 II)?
Yes, why not. this is a very low noise supply

thank for sharing! I have a pulse transformer with parameter: ***N1 [4-5] 0.15 / 160T, N2 [6-10] /0.35/11T,N3 [1-2] 0.15 / 14T cross*** It has 2 secondary winding, how can I use it in this circuit?
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!
What happens when you short the output?
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
Hello! I simulated the circuit you made (by using a square wave instead of the UC3843) to check the components choice. I noticed a big inrush current on startup, approximately 50A (you have very big caps) when the demand of current is high. How did you manage to reduce the inrush so it does not destroy the components? Secondly, can you upload the calculus you used for every components? On the TI datasheet components calculus are for a flyback SMPS, and whan i tried using general formulas (from Phil's labs) i had really bad results with a lot of ripples. I wouldlike to do the calculus by myself. Thank you!
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?
with usb type c why don't you also try to make pd trigger board with let say dip switch to select output voltage then will have a wide range of selectable output voltage.
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.
When I graduated from school some years before the dawn of the Internet, I thought that I could do anything. Give me an electrical engineering problem, and I could solve it. Hardware, software, everything. How naive I was. Back then I knew the fundamentals; nothing else. Every time I watch this man’s videos, I see a real expert. I hope that everyone watching appreciates the quality of these works.
Thank you Neil 🙂
another good project.

Hello Mr my name is kassahun Tamiru from Ethiopia Africa as you explain digital energy meter measure Active energy reactive energy ,apparent energy , active ,reactive ,and Apparent power and also digital energy meter measure instant current , instant voltage ,power factor and display any tamper event on meter LCD like Battery status , reverse connection ,ground , terminal open and Etc , my county single phase system voltage standard is 220 V and we use digital energy meter but our meter canceled the previous stored cumulative energy when our voltage decrement to 170V and below what will be the Reason for meter canceled registered kwh
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
Thanks for sharing very interesting topic as the above board shows the energy meter design for 220 nominal voltage what will happen if the voltage level below 220 V or 100V
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

Traces for voltage drop sensing on shunt resistors network is far from best practices. You included a noticeable part of copper traces as path for current. It will cause less stable real current when the device is heating. It's not an issue for a hobby project, but you learn here people to do things properly, right? So, that's why I'm pointing this here for you.
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!
Nice my friend

Hello and thanks for the video!Can I only switch the Mosfets for having a power supply of 120V?
you should change some capacitors and the MOSFETs because your input voltage is higher than the voltage of these components
@@MyVanitar Thanks for the reply.The capacitors I have to change are C5,C6,C7 am I right?
@@upbgenoob5488 honestly the PCB should be modified to follow the higher voltage standards, but what I told you was the minimum action, otherwise those components will explode
Do you ever see lower ESR than expected and would this mean the capacitor is bad? I have a 50V 22uF through-hole electrolytic capacitor that I suspected may be bad on a power supply. Using the Aideepen LCR-TC1 component tester I measure 24uF and 0.47 ohm ESR. Using an online chart I think the ESR should be like 10x that, but maybe I'm mistaken. I had pulled this one because it appeared to not have continuity to GND on the board and I heard that was one way to test for bad caps.
in one case you read very low ESR and that's when the capacitor is shorted, which happens mostly for ceramic SMD ones. But in your case when the capacitance is okay, I am suspicious about your LCR (if it's a brand or a DIY) and the measurement frequency (use either 100Hz or 120Hz if your LCR meter is one of these, for the electrolytic-type capacitor is above 10uF). take the capacitor out of the circuit and test it again, it might be a resistor or an inductor in parallel.
@@MyVanitar The capacitor was already taken out of the circuit. I didn't make the meter myself but it is a cheap (under $30) meter from Amazon. I just recently got the LCR and this was the first thing I tried with it, so if it's not accurate, I'm not sure. I can't set the frequency myself, it's pretty much automatic, you stick the part in and hit a button and it does some things to detect what the part is and display info.
with higher frequency, the ESR value drops so I think your capacitor is fine, especially when you read 24uF. Test it with some faulty capacitors
@@MyVanitar That makes sense, so it's probably not using the ideal frequency for this capacitor so it looks weird. Thank you. I don't have any known bad caps around to test but I am trying to find bad caps on this board so I guess I'll pull and test some more and see how they look.
usually, the frequency of such devices is fixed at 100KHz, used by many manufacturers and datasheets to show the ESR, and also for marketing to show the ESR of their components is low. those online tables are rough estimations and they do not mention the frequency. you gain experience with some repairs. mostly ripple and heat cause the capacitors to fail
Sir circuit working super but inductor and shunt resistance get more heat😢
