Fantastic Haaseb! That's exactly what I asked you several times. You should do the sane also for the *MANY OTHER* switching power IC's are around nowadays like Viper12A, Viper53, DH321, NCP1200P100, TNY268 and many more!! Please consider making these videos ! Thanks! I'm writing a script on testing the TL494 this way, following this video! Thanks ALOT! !!!!
sir, thank you for finding time to respond to our concerns. Much appreciated. i deal a lot with smps, i love electronics and have been attempting to learn for many years. Am still learning and your channel has been very helpful. you take time to teach and you know what you are doing. thanks. I have a question regarding testing of the IC as you taught here. Can we apply the same approach to test other IC where we are in doubt? Thanks. I know the pins are not likely to be the same, but it will be helpful if we can leverage on this knowledge.
Hello Mr Haseeb. Thank you for your videos on CZcams. I have a question: in a smps device like your device in this video, there are two step recovery diode (high watt). It has not puls transformer. Please explain this topology.🙏🏻
Hello Sir, Really appreciate your unmached explaination . Many many thanks for it. Can we measure the base voltages of main power transistors after removing them pls?
dear haseeb sir i found out that in aneng Q1 inorder to measure in high frequency we have to go to milli volt(@second button in meter) and select AC mode then it will accurately display frequency from 100khz to 5MHZ.(it is instructed clearly in manual :) )
SA. same pcb model I have power supply 12 V 20 A. There is no load and fan and cooler heat sink is not installed in the case mosfets (j13009-2 x 2 pcs) are overeating that is normal or not? If not what may cause that?
Salam M Haseeb, i built a charger based on a TL494, the voltage adjustement works but when i put a load, the voltage drop to zero volt. Can you please indicate the check points to troubleshoot that issue. Thanks.
Haseeb bhai thank you very much for your immediate response . Your videos are very helpful for so many people.
Thanks again and good night 🙏
An excellent video ,, thank you very much sir
You are most welcome

Good video brother what desolder u r using
it is WELLER WR3M rework station
thank you very much for sharing the idea
You are most welcome
wow very excellent explanation
Very informative vedio. Thanks
Very good informative thank you brother why should you not try to make one DIY inverter circuit of tl494
Best regards from Philippines 🇵🇭
thanks a lot dear brother
it need time but i don't have spare time, but i will try to manage it
@@HaseebElectronics I can understand that take your time and take care 👍

Zbrdast sharing
You have explained it before how to test such IC. :-).
Great work
Thank you so much dear sister
amigo muchas gracias
Gracias, siempre un paso más allá que otros. Like y comenterio... cumplido...
very nice video, 😍😍😍😍😍
Many many thanks
Sir , Which digital storage oscilloscope is best ? I want to buy . Will you pls. help me?
for routine work 2 channel, 100 MHz, 1Ga Samples/Sec, DSO is awesome
you can select Hantek, Sigilent, Uni-T, Regol, FNIRSI while comparing prices
I sincerely thank you for the reply.

exactly yes

Nice safe debug technique
Nice.
How can I detect good and bad I. C in an electronic card. What is the fast and easier method of troubleshooting electronics card. Thanks

Hy sir, saya mempunyai inverter dengan ic pwm sg 3525. Saat inverter di jalankan mengapa suhu ic sg 3525 pada pwm panas? Terimakasih
Ottimo spiegazione grazie. ⭐⭐⭐⭐⭐
Excellent
Thank you so much 😀
Dear I have dc to dc power supply no output. Need your help to fix a power supply. Input from 95dc to 295 dc outputut. 26dc
please send its model number, pictures to my whatsapp 00962-79-5324272 or gmail id ashraf4ta4
❤️❤️👍
thanks a lot
salut bon mardi aprem 🙂
👍👍👍
The desolder machine has a good noise to relax and sleep.
May you help me to read ic pin numbers they tend to confuse me
👌👌👌👍
👍🙏
best regards
👍👏👏
so nice of you
I got 26kh at pin 8 and 11. But the voltage is 1.44v is the IC faulty?
sir ka7500 use smps 5v 40amper to 48 v how to change please sir
