Greeting from Thailand!!! I just come across your useful video and would like to thanks for sharing these knowledges to all of us. Look forward to new valuable video.
Hello my brother! Another fine video. This is very valuable information that I was not aware of but needed for a very long time. You are truly amazing and I am learning so much from your videos. Keep up the good work and thank you so very much for making me a better technician.
Hi in my circuit I have PWM ob2287cp. in minute 4:46 you talk abut frequency 100Kohm = 65 Hz . and in pin 4 I have 15K resistor. have a 2 question. 1. if the resistor is 15K what will be the frequency of the PWM. 2. And how do I measure the output voltage on pin 8
Hello, I want to send you a greeting and also congratulate you because you have achieved a wise balance between theory and practice, I ever remember reading a phrase that I liked very much, the phrase said; "The difference between theory and practice is like the difference between unclear ideas and common sense", I understand your madness for electronics, the same thing happens to me, since I was very young I had an immense passion, I still have a lot for learn, although I have not learned much, I have the ability to recognize people like you who have the compass well oriented in their knowledge, I appreciate everything you do, it would be great if your channel had subtitles but it is not a request. just a suggestion since you would reach many more people anyway the content of your channel is excellent, I send you a hug from a distance and I hope this translation is understood since my language is Spanish, I understand something from English and Italian but not like to make a speech, Greetings !!!!!
it is my pleasure. i am thankful for your valuable appreciation. i will try my best to add subtitles to my videos please accept my best regards and special thanks

good information brother...I have a question. since the pwm ic was damaged and has been taking out from the board..is the auxiliary winding still outputting Vcc voltage? if so..that means we can easily identify the voltages for the pwm ic..
For OB2268 / OB22 69 ( VDDon= 10.5 & VDDoff = 16.5 ) And for SG5841J (VDDon = 16V & VDDoff = 10 ) So Brother Mohamed those IC"s are not equivalent..!! The voltages are reversed and not identical.. Please check this. God bless you.. Greetings to you..
there are many ICs have all 4 pins as source pins if you can write all pin functions then i can try to find for example pin 1 is connected to optocoupler, pin 2 vcc capacitor, pin 3 resistor, pin 4 transformer, pin 5 to 8 are ground etc or send pictures of ic closer area front and back side to my whatsapp 00962-79-1161084
Hello friend, 1. I have a power supply with PWM OB2287CP I tried to replace it with OB2279 Instead of getting 5V on pin 3 I get 17 V. Is it even possible to swap them? 2. After I replaced the OB2287, the 0.2 resistor, 10N60, fuse, the power supply gives me 24 V But when I load it, everything burns out.
Dear brother how can I find replacement for this componen OB5269CP easily, as in my place hard to find in any shop here, thank's waiting for your feedback and advice as well, From Timor Leste 🙏
Hi. I have a 1500w 12v inverter Chinese with an unmarked 16pin pwm ic. I cannot identify it.. so far vcc = pin 15, gnd pin1, E1 pin7, E2 pin10 , pin 3 5,6 and 13 nc
How to contact you sir,i am a 73 years old person and want to clear some doubts regarding Smps boards with pwm ic driven by some modules which are in black epitoxial coatings. Can we remove and still make tjem to work.

Very cordial of you, I value your quality as a Person !!!!
Such a wonderful sharing Nice 👍👌👌👌
Thank you so much
Good explanation
I don't know how to select the type and size of heat sink
Kindly do a video on that
اللهم بارك وفقك الله لما يحب ويرضى
thanks a lot dear brother
MASHA ALLAH as always very interesting and informative, very nice sharing, Imran from KAUP STUDIO
Jazaak Allah khair dear brother
It is more than informative, it's extremely important to solve a lot problems when we do not find the damage part; thanks a lot.
Yes dera. It becomes a bottle-neck when we cannot get a number of cracked ic or it have no number or we cannot get equivalent part
@@HaseebElectronics That's true, it has happened to me a lot of time; from now on, I'll try your recomendation. Thanks again.
Lk 7 good job 👍👍👍👍
Thank you so much
thanks a lot sir for such a valuable video 👍👍
So good sharing brother 👌👍👌👍👌
Thanks bro very informative 👍♥️
Always welcome
Great one my friend Big thumbs up
Big thanks
39 You should be familiar with the electrical circuit diagram. It's an attractive video. I support it♡
Yes, thank you

So Brother Mohamed those IC"s are not equivalent..!!
The voltages are reversed and not identical.. Please check this.

Greetings to you..
Thanks for sharing good information my brother
i realize I am kinda randomly asking but does anyone know a good site to watch new movies online?
@Andres Brett flixportal xD
@Harper Karsyn thank you, signed up and it seems to work :D Appreciate it !
@Andres Brett you are welcome xD
Aoa brother i need your number because i need some help from you about a burned ic whose number are not read able
Sir
Do you have the datasheet or equivalent of 1D310 ic. It has 8 pin
Superb Dear ❤️👌🏻
Many many thanks
Thanks lot. Very useful video
And please help me to open that website in English that your link open by another language thanks again.
yes
it is in russian language
just use translation option in your internet browser to translate into English language
Nice information sir. But if we 14 pin or more pin ic. Then how to wind number sir
Very very nice teaching sir thanks,
Most welcome
Awsome video! Great link too. Thanks!
Thanks a lot
Link is in the end of description
Dear sir, I want to know the qw 3862(dip) 8pin , equivalent ic numbers
SD4870, CR6848
In frontech monitor SMPS the 8pin has no number. One side all the 4 pins are at -ve. What will be its number?
there are many ICs have all 4 pins as source pins
if you can write all pin functions
then i can try to find
for example
pin 1 is connected to optocoupler, pin 2 vcc capacitor, pin 3 resistor, pin 4 transformer, pin 5 to 8 are ground etc
or send pictures of ic closer area front and back side
to my whatsapp 00962-79-1161084
Nice work great video
thanks a lot
Can you help me for a equivalent of atc9531 which is available in market
Hello, I have an IC that I can't find a replacement for 6C17744 . Can you help me
Thanks
Good work
Thank you so much 😀
thank you very much for helping me
very useful video 🤠🤠
best wishes and special thanks
beautiful idea
Many many thanks
Hello friend,
1. I have a power supply with PWM OB2287CP I tried to replace it with OB2279
Instead of getting 5V on pin 3 I get 17 V. Is it even possible to swap them?
2. After I replaced the OB2287, the 0.2 resistor, 10N60, fuse, the power supply gives me 24 V
But when I load it, everything burns out.
سبحان الحمد لله رب العالمين والصلاه والسلام على اشرف المرسلين سيدنا محمد

Do you have instructions for when you can't get schematic and they have removed the codes on the ic?
How to contact you sir,i am a 73 years old person and want to clear some doubts regarding Smps boards with pwm ic driven by some modules which are in black epitoxial coatings.
Can we remove and still make tjem to work.
first of all i am thankful for writing your comment
most welcome sir!
my whatsapp number is 00962-79-5324272
gmail id is ashraf4ta4
that coating is really a horrible technique from chinese manufacturers to conceal their designs
if that item is suspected, most of time replacement is most preferable solution
or reverse engineering is to be done to overcome the design structure
