| Oct 8, 2021 at 13:25 | comment | added | DKNguyen | You need to read more about the fundamental basics of buck converters before building one, let alone one with your own modifications. You skipped a few steps. Do you even know why Q2 is there? Or why any component (transistor or not) is even in Q2's position in all buck converters? | |

| Oct 8, 2021 at 12:15 | comment | added | Bimpelrekkie | This video by Dave from the EEVBlog explains what happens when you apply a voltage to an inductor (relay) and then suddenly break the connection: back EMF: youtube.com/watch?v=hReCPMIcLHg Sure, Dave powers a relay but that's also an inductor so the same thing happens in your circuit. | |
