Hi Sir, can you please explain the role of that 100nf capacitor on tl431 that is place between the reference pin and cathode and also the capacitor that is always in parallel between the collector and emiter of the optocoupler in SMPs
Hie sir I am. working on tl494 operating car radio amplifier. It is triggering high current on pin 16 current feedback and turn off the outputs. At times it works well on low volume but blows the output transistors. My question is how can I correct such an anomaly? Aaron from Harare Zimbabwe
Sir, mai 12v to 12v DC Dc Converter banana chahtahu Transformer se, likin isolated hona chahiye. Mai Flyback aur Uc3843 use karta hu. Ferrite Transformer EE28. Likin mujhe proper output nhi milraha..thoda load deneme jayada Input current leta hai. Output per load 2amp v sehise nhi le paraha. Mosfet bahat heat hoti hai. Mai 60khz aur Pri 37T, Sec 37T use kya hu. (Flyback, One mosfet one Diode) Sir please mujhe Transformer ka Calculation bataye aap.
Mash Allah good video
Excellent thanks for sharing this informative video keep sharing❤❤
So nice of you to appreciate my work. 🙏
you have a lot of experience buddy
Amazing aa always. Waiting for current control for variable ATX Power supply
Excellent
Your appreciation is highly valued.
👍
Assalamon Alaikom Sir,not active like option for me,thank you for sharing trace,unfortunately in tvs test video didn't asked my question 🎉 6:36

I think JSs diode is BAS21LT1,Is this right? 1:34
exactly yes. it is SOT-23 package BAS21L diode

Are you get cold?!
no. i was feeling little bit upset. but now i am fine
