HTML-код
- Опубликовано: 15 сен 2024
- Hello guys, today in this video i have showed you an powerful 24v 6amp SMPS. This circuit uses OB2269 IC. The circuit has an adjustable output voltage from 27v to 17v. It has all protection like over current protection, short circuit protection . I have used EE35 transformer with an air gap of 1mm. I have use IRF840 MOSFET, you can use any N channel MOSFET working at 500vdc or above. Feel free to ask any question in the comments.
HAVE A NICE DAY :D

Wow! Great job! As always super! I am very glad that I found your channel! Thanks for the circuit and PCB! Like from Uzbekistan!
Thank you very much bro 😄😄😄😄😄😄
Sir ic ob 2269
Could you please provide the detailed specs and design information for a 230V AC to 24V DC, 6A transformer for use in an SMPS application? Thank you!
Great job KD!!! now need to make 24volt 500-800mah small smps!!! and also need to show circuit design and printing details technic full video , Thanks KD-Love U !!!
Thank you very much. I will sure make a small SMPS soon :D
Very well presented with a thorough explanation and test. Well done!
Thanks bro
Inverter 12-220 on your project turned out on the chip tl494! Thank you! We are waiting for you to new videos with a clean sine on the way out!
yes i will make another 12-220 soon . thanks :D
Its a simple flyback regulator with RCD snubber, and snubber can't remove all voltage spikes, so this 500v mosfet is not the good choice it will get overheated and die soon ....... Although good video,.,.. make a video on active clamp circuit instead of rcd snubber or push pull regulator..... That will work with 500v mosfet
Bro u r great...
I was searching for this level of videos on RUclips for many years but all youtubers are busy in playing some stupid DIYs..
There are some who are making these intermediate level videos But their numbers are very (u know). Also those are in american or British.
I like ur videos but want some more explainations..
Thanks bro for your feedback. I will do this from my video
Please make a tutorial for winding a ferrite transformer completely without cuts. Thank You
I want 24v 2.5Amp what changes i need to do it??
I wont details explanation of this project wich components for what purpose and how is work and what is do nice video
Please explain more the winding of transformer. Why are you hiding the winding part in video? Also there is no information for winding transformer in the schematic! Why? Please complete your tutorial.
Could you make a video about Current and voltage adjustable power supply project?
For example 0-30 volt and 0-6 amper adjustable power supply for our electronic labs
Ya sure I’ll try this.
thank you... keep it up awesome! your fan from Philippines
Good circuit which have overcurrent and short-circuit.
I want to make a 30 volt 10 ampere bench power supply. I did not see your current control in it. I want a circuit that can control current and voltage. Can you help me make a circuit like this? And Volt 2 to 30 wants to do that. Hope you help me.
i will make it soon :D
Excellent project go on Sir.
Thanks 😊
Can You Tell me when You wrap the tranformer on the primary side 1 turn , is that feedback Corred. Thank you
Sorry but can you please simplify your question
@@kdcreativity6201 sorry friend what is it that you wound the transformer with 1 turn of wire . A bout at 4:39
@@Mechechao9382 it’s the auxiliary winding. It contains 6 turns and that 1 turn is just an example about the starting point and the winding direction 😊
This is interesting buddy, great job, I'm going to assemble it hopefully it'll work
Is it a typo or what, on the list you wrote 222M as of 222 MegaOhms or?
Thanks bro. Best of luck 😄😃. That 222M is a capacitor of 2.2NF.
Good job! Everything is informative except for transformer winding. Where is the end point of the second part of primary winding? Can you upload the whole video of transformer winding? Thanks and more power.
Your most welcome. You can pause the video to see the ending point. I have clearly shown it in the video. If you want to ask more about the transformer then you can message me on messenger. Thanks
Thank you very much! @@kdcreativity6201
This is some good work.
Thanks :D
nice project . really useful and economic . thanks
Welcome bro 🤗
Just an order for the IC, and can you create tutorial about creating PCB and exporting for single board in EasyEDA or proteus ( preferably proteus).
BTW, thanks and you got 1+ sub from Tanzania
I have already made a video on pcb making and I will very soon make a video on pcb designing and exporting its files. Thanks bro
@@kdcreativity6201 good work brother.
Stay safe and keep up the good work
@@raymondmichael4987 thanks 😊
Very nice explanation
Thanks 😄😄😄😄
Nice Video
I think we can change output voltage range with TL431's connected resistors value right?
can we make a Li-Ion battery charger adapter(for 4 S battery) with this circuit (need 16,8 volt CC MODE)
Thanks. Yes you need to change the feedback resistor for changing the output voltage but if you increase or decrease the voltage more, then you have to change the secondary turns also. You can get 16.8v but not CC
Hi nice video and project I'm working with Arduinos but never tried to make anything high power circuit can u explain each component in a video thanks
You can message me on messenger for more information
Great work , improve more and start production
Thank you very much broo :D 😄😄😄
Hello friend, I am David, one of the followers of your channel, I want to ask you a question that you should modify so that it has a 30Vdc output. thank you so much
Very easy, change the secondary to 10 turns and change the 1K feedback resistor to 680ohm and don’t forget to use 50v capacitors at the output
Great!. why you don't put a ready build transformer? or can you recommend a ready one!
thanks 😄We cannot use a ready build transformer because we need to design the transformer according to our requirments
@@kdcreativity6201 I understand, but what if you want to make 100 of this board. Do you want to build all of the transformers from zero? 😅
@@mahereldebuch34 then we need to use machine or contact a manufacturer 😆😁
How to decrease a smps power supply amp?there r 3 wire in secondery if I cut 1 wire is it reduces if yes then any other malfunction can may happen?
Just decrease the number of wires in secondary
Very nice work bro. Can you design a buck converter for my solar? Its input volt is 60-72 and output is 12-24 volt 30 amp.
Thanks. I will make a buck converter very soon :D
@@kdcreativity6201 Thank you boro and wait for it.
good job bro keep it up❤️❤️
Thanks
At what frequency does the circuit work?
Today I really enjoy your videos.
Can we use UC3843 as the control chip?
Every chip has different pin out and functions so you can use.
So what type of IC can be used to replace the Ob2269 IC. because it's hard to get it
isn't uc3843 a different pinout?
Awesome bro...🫵🔥🔥🔥
Share diagram and component list for 20 amp DC 24v.

You have used EE 35 cores. From where can I buy this ? Can you share link . Also link for buying other important components.
Remove it from a old atx psu
Hello sir,
we are hobbyist in electronics, I have no formal education, basic idea from RUclips, I have seen many of your videos, so I request you if you give me the pcb gerber file of this circuit, I would have ordered the pcb from Jlc pcb, thanks
Can u tell me where can I buy SMPS transformer for 24 volt?
You can get the transformer online but you have to rewind it according to the given details
plz tell the primary inductace value for ei35
What should I do to get almost 8 ampere of current at 24v
The power is limited to 150W in a flyback power supply. You can get more but not recommended
Mbr20100 k place per mbr2045 ctg use kar sakte h kya
Yes
😊
What ic can be used instead of ob2269???
How to set operating frequency range of this ic
Dear sir
Can you share transformer winding data. In video you explain very fast.
Please check the video description
Dear sir please provide Gerber file I want to make with jlcpcb
Yo bro, I want to make same smps for 12v dc, so should I make the change in winding of secondary? Instead of 8 turns should I do 5 turns? Please reply
Yes do 4 turns and change the 1k feedback resistor to 2.2k
Dear friend Is it isolated
Yes
Can I use RL 257 at the place of RL207
Yes
Sir , plz make 50-0-50v smps for amplifier
Ok
Can i remove over current 6a to increase 10a 24v
The recommended maximum power is 150W
Plz make +-24 Supply 5amp
Hello
Bro where to buy this ic ob2269 ?
I have purchased it offline
What IC can be used instead of bd2269? And what is emi filter details?
And if i use two irf840, can more amp out?
??...
it has over voltage protection?
You need to add a MOV after the fuse
Can you please able to list the components which are used bro?
Check the description
Wire in gauge?also possible to use a str module ?
You can use str module
@@kdcreativity6201 can I get same amp and volt ?also can I use pc smps main transformer to make 24v 6amp.pls share ur opinion.also many thanks to u 👍
Is it 23 no wire?
You will get the same power but don’t use pc transformer as they don’t have air gap
@@pikludutta5315 ya
Bro is this pcb avilable
Tell me pin no. Of start and stop of smps tranformer
See the video
What is working frequency of this tranformer??
70khz
Can I buy this complete coard
Sorry I don’t sell
How to calculate the frecuencia of this integrated
Check the data sheet of the ic
Can I buy pcb online ?pls give link
Sorry I don’t sell
i think 1mm air gap its to thick
Sir what is its operating frequency?
75Khz
@@kdcreativity6201 Where can I get the transformer, can I remove it from any old thing?
Yes. I have also removed it from a old atx power supply
But 0.5mm wire can handle maximum 68KHz frequency as 100% skin depth. Will not this transformer give sound or heatup?
@@MrRais66 actually the diameter of the wire is a bit less than 0.5MM and also the working frequency is between 65-75khz (depends of the tolerance of the rt resistor) so there are no problems
Can i get purchase limk for EMI filter
Take it from old circuit boards
Hey kd can we increase the amps upto 15a ?
The power is limited to 150W
Can I use 472j 100v
No
Then, can use 2A 473j
Its a snubber capacitor so please use a high voltage capacitor and you can’t use 473j

Please reply
1 inductor specification and equivalent
2 is it possible to make it on zero pcb instead of proper pcb board
Also your transformer making video is not sufficient how u did that why are u so hurry in making this video u haven't explained the circuit also it feels like you're copying someone's idea and making it for RUclips views
1.Use inductor between 20uh to 30uh on a iron powder core( yellow colour toroid)
2. You can make it on zero pcb
Thanks for replying can we talk on Facebook I have texted you there plz reply
Yes
