[@mariodistefano2973]

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! !!!!

Welcome!

Simply excellent!!!! My humble thanks!!! This was interesting. 👍

[@chibuzo7746]

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.

[@mobilewildrift]

thank you very much for sharing the idea

[@HaseebElectronics]

You are most welcome

Good video brother what desolder u r using

[@HaseebElectronics]

it is WELLER WR3M rework station

[@AnandKumar-ym9yw]

You have explained it before how to test such IC. :-).

[@MarkPrince1317]

Very good informative thank you brother why should you not try to make one DIY inverter circuit of tl494 Best regards from Philippines 🇵🇭

[@HaseebElectronics]

thanks a lot dear brother it need time but i don't have spare time, but i will try to manage it

[@MarkPrince1317]

@@HaseebElectronics I can understand that take your time and take care 👍

[@NewEra6348]

Very informative vedio. Thanks

[@FishingNOutdoorFun]

wow very excellent explanation

[@sunilkarki5738]

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 :) )

[@HaseebElectronics]

exactly yes

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?

Gracias, siempre un paso más allá que otros. Like y comenterio... cumplido...

[@ahoorapersia4698]

Hello Mr Haseeb. Thank you for your videos on KZbin. 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.🙏🏻

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?

[@aritrasinghachowdhury3227]

Sir , Which digital storage oscilloscope is best ? I want to buy . Will you pls. help me?

[@HaseebElectronics]

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

[@aritrasinghachowdhury3227]

I sincerely thank you for the reply.

I got 26kh at pin 8 and 11. But the voltage is 1.44v is the IC faulty?

[@voltronicug]

May you help me to read ic pin numbers they tend to confuse me

[@nayanjagirdar8408]

👌👌👌👍

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.
