Hi. regardless of the project and the design can i replace the ( MOSFET and the coil and the diode ) with higher quality that can give me from 24V input 20amp max an output (12V 40A or near it ) up to ( 48v 10amp or near it )? you know that i have a transformer 24V 20amp and i need a boost/buck converter that gives me 12V 40amp up to 48v 10amp

I have a general question, Can a dc-dc step up module be used to maintain a solar panels output at 12v 2. 5amps, when panels out drops significantly? My solar panel is 12v 50watts one and I see the output fluctuates when I connect a 19v, 3amp laptop charger(around 60watts, I wonder if one of these step up modules can help

Hi. Very nice video, GreatScott! As always.
I have a doubt, though: i may be wrong, but isn't flyback the name given to the transformer in a buck-boost converter topology? As long as i know, you implemented a buck-boost converter only. The flyback converter should have a transformer between circuits, shouldn't it?

Great video man! Thanks for sharing practical knowledge. The position of the switch must be on the low side for practical reasons. With high side switch, there will be negative voltage on the source when diode is conducting and you can not use bootstrap method to drive the MOSFET than. You saved me time, thanks again.

I can say that the rather low efficiency of ur circuit is due to the 7805 linear regulator used to power the attiny with 5 volts.
You could use a smaller Buck converter module for that but that'll totally destroy the diy aspect.
Great work as allways

Thanks for your contribution to the development of knowledge, I have learned a lot about this type of switched sources.
Tip: You may be able to extend your tutorials to design half brigde or push pull converter topologies.
Thank you!

could we use LM358 or any other op-amp for the same purpose because MCP602 Isn't available in my region, if yes then what modifications do i need? please reply ASAP! because i've been stuck at making my own one for a lab bench power supply!

Hi GreatScott!
I have some interesting question to discuss with you!
if we can build the buck/boost converter into one circuit then why there are still some people who build the buck or the boost converter circuit separately?

Hello,
Can you guide me for limiting the output current to 350mA of a power supply (with output 250vdc, max output 15Amp. Should I simply add 0. 22 Ohm 10W (9 Resisters) in Parallel before load?
