Guide to the TL494 PWM Chip

[@mahoneytechnologies657]

This is a great technique to explain how to use this IC, NOW CAN YOU DO THIS FOR ABOUT 100 million more ICs , or can we get all of the IC manufacturers to do this !

[@ElectricMonkeyBrain]

lol. well I thought I could do this for popular chips. Know any popular chips?

[@mahoneytechnologies657]

Will the Ubiquitous NE555, HC4046 PLL, the LTC699X Family of Timer Blox parts ( there is a great online design tool, and a ton of App circuits, I wrote many of them ), The LTC CURRENT SENSORS ( just look at LTC note AN105 to get Inspired), speaking of App notes, Jim William’s App notes’, any of them, are outstanding in every sense - AN65 and AN47 should be owned and studied every Engineer and Technician! They teach how to think like a good Engineer, I worked with Jim when he wrote AN65, that’s where I got my real electronics Education! This would be A good Start. You present your material very nicely, simple, in little Bites and very clearly explained, to be able to do this is a real Tallent, Keep it up! The reason I list the parts that I did is because each of these parts can be applied to so many different types of circuits. Like the NE555, when it hit the Market it was presented in a brocher showing it being used in 10 very different types of circuits, I bought ten of them when I was in the USAF AND BUILT all ten Circuits and more, what A time!

Actually yes I was thinking of the 555. HC4046 is also interesting. Not sure when I will get to them though. I seem to be slow at producing videos, I am still learning. @@mahoneytechnologies657

[@mahoneytechnologies657]

I was thinking of doing some PCBs for studying these three parts’ now I Will.

Short and straight to the point, it just answered questions that has bothered me for a very long time ... (Over voltage/current protection) Thanks a bunch for sharing ✌️😇

[@ElectricMonkeyBrain]

thanks. short and to the point was my aim :D

[@t1d100]

Wow! Super production. Super teaching. And, a powerful IC that I did not know about. Kudos!

[@ElectricMonkeyBrain]

thanks a lot

[@michaelsintros292]

Perfect video. I was looking for info about TL594 but it looks like this chip uses basically the same principles, so this will prove immensely helpful.

[@bhuiyanimam7657]

Excellent video, would love it if you made them on more ICs, like 555 and TL431, etc

[@Paul_VK3HN]

Excellent explanations, what a neat little chip! Would like to see a video on how later TI chips improved on TL494, for example, TL598

[@tomsiri1960]

Clear, precise, comprehensive and complete. Perfect!

[@peters9929]

Fantastic info , no BS just simple facts thanks for doing video , well deserved sub

[@Taylor_26GE93]

Great video, just stubbled across your channel and subscribed immediately. Keep it up!

[@majharulislam5950]

Excellent explanation

[@Nāmarūpa1]

Thank you. Easy to follow, good pace.

[@evgeniytoropov9455]

Отличная информация, всё наглядно и понятно.

[@SignorZukini]

Great, clear and concise video. Thanks!

[@aravindadas567]

very nice information in this video about all application of TL494 ic.

[@FixDaily]

Hi, I'm confused. 4.42 how can you do soft-start with a ratio of 1:10 without disturbing the dead time?

[@theinnovati0nlab782]

Very nice! I am currently working on a high power 5000W synchronous dc to dc boost converter system and I am planning to use TL494 as well. Great video. Success wishes! 👍👍 The Innovati0n Lab💥

[@unrealcrafter2671]

What is pin 3 for?

[@murraymadness4674]

Thank you. I'm trying to increase the voltage and amps in this cheap dc boost board that keeps blowing up. So from what I understand, it should work just the same if I increase the ratings of the mosfet and diode.

[@king_james_official]

i like your username a lot.. very fun. thanks for the video. it seems you forgot about the feedback pin though TwT

[@dalenassar9152]

At about timestamp 4:00 is the common connection of the resistors connected to the bottom of the capacitor? There is no connection dot there. THANKS FOR THIS VIDEO...my first look at the TL494... --daLE

[@unrealcrafter2671]

For it to work it would be connected

[@yasirshahzad3732]

Very well explained

[@derekschwontz9072]

Great tutorial

[@ElectricMonkeyBrain]

thanks a lot

[@gkdresden]

The pulse-by-pulse current limiter should also work if you put the current shunt at the primary side of a flyback or push-pull converter between the MOSFET sources and ground. But in this case you have to set the current according to the primary voltage, to limit the current at the secondary side. And you have to make sure to set the current twice as high because it starts from zero and goes to its maximum value. This needs to be twice as high as the average current you need at the primary side. You forgot to mention the feedback pin. It can (should) be used for compensation (f.i. by use of a 10 nF capacitor from the non-inverting voltage error amplifier pin to the feedback pin). You can also use to shut the controller down by connecting it to the reference pin (f.i. by use of an opto coupler). But you can also shut down the oscillator by connecting the CT pin to ground. For setting the output voltage to a voltage higher than the reference voltage you can connect the reference pin also directly to the inverting input of the error amplifier in order to save a voltage divider. So you only one voltage divider from output to ground.

[@coucouj2781]

Sir what about the feedback pin :/

[@fahirkutsaldoğan]

çok güzel,elinize sağlık👋✌

[@hichamtassi1753]

Hi there, any clues on the PIN3 ? thanks

[@armandine2]

it seems not? perhaps next time

[@tolgadabbagh1877]

very good video thanks

[@ChrisHalden007]

Great video. Thanks

[@ElectricMonkeyBrain]

Glad you liked it

[@pcbekri340]

thank you soooo much man you are great

[@stevenbliss989]

Bizarre that +ve input is the feedback on both error amps! I have a love hate relationship. It is VERY STABLE, but the lack of push/pull outputs like in the SG3525 REALLY SUCKS!!!!!!!!!!!!!

[@ziadfawzi]

Thank you so much

[@yahyanasiri7062]

excellent

[@pinkkitty6553]

thanks a lot
