DIY Buck converter - TUTORIAL

In this video you will find some examples on how to make your own buck converter circuit using the P-MOS IRF4905 but also the IRFZ44N N-MOS. Also you will learn why do we need all those components. You can find all the links for schematics/codes below. I hope that you'll enjoy the video. Stay tuned for the BOOST converter tutorial.
