As always really nicely explained!

The way you explained the voltage feedback comparison process for regulation in the dc-dc ic is simply art. The art of explaining complexity so well that it suddenly becomes simple things in cooperation. Great video.

Checked lots of SMPS tutorials but your series was the most comprehensive I've found.

I thought I would never understand the function of electronic components. Thanks to your channel. You put things in simple words, in witch I could understand & not sound like my class instructor speaking in a foreign-language. Thank you

This video is excellent and it was made 9 years ago... I liked that 1.21GWatts reference xD

You really saved my day after i heared the Linear Voltage regulators are not very efficient, unless you want to heat your whole room. At first i was very irritated what component values i should use, but you explained the Voltage Divider very well, thank you very much 👍
