This is the best electronic channel on youtube.
thank you for your kind words!
I'm an electronic technician but i didn't know the working principle about this type of converter
Thanks for the video
Glad you liked it
Well, charge pumps are definitely not forgotten and very well used, especially in cases where higher or negative voltage is required, or just a more "quite" voltage is needed (without switching of inductors for example), but your video is great, as always! Keep going!
Great point!
Great work !!
Thank you so much Dada!
truly outstanding brother😍
Thank you so much 😀
I’m aware of a gigabit Ethernet PHY that uses an internal switched capacitor regulator to provide its core voltage rather than a switched inductor or more commonly an internal LDO. It performs just as your video describes: not as efficient as switched inductor, but only requires diminutive 0.1uF to 0.22uF ceramic capacitors and still more efficient than LDO which would require similar capacitors anyway.
Good info.
Glad it was helpful!
awesome
How does changing the duty cyle affects the output?
How could you use this to generate the high side n fet in an h bridge?
It strikes me that this could solve boating to 12v (or 6v for gan) providing a continuous boosted voltage for the high side fet so it could have 100% duty cycle.
small doubt brother, how long time MOSFETS Q2 & Q3 should turn on to charger the capacitor as same source voltage, kindly give the clarity..
Hey, you told that it produces low noise, it would have been better if you have one some tests on those to verify it.
I am sorry. I don't have any test results with me
I watched yuor exelet videos about MOSFET drivers but i still can not configure what is the problem witg my circut, I use UCC2237p driver IC with IRF3205 mosfet 30ohm gate resistor 12V zener diode and 10kohm G to S resistor 12V suply and 40kHz square signal on input and eaven with drain not connected to anything it's destroing my mosfet I don't know why. Mayby you could help me
Could this handle an input voltage of 40 volts?
no
