Can I use this switch for ON/OFF and 5V DC? : r/AskElectronics

DC to AC to Arc (lighter): Will this also work with 5 V instead of 12 V? What parts to adjust? : r/AskElectronics

Anybody can explain what features this 220vAC to 5v dc circuit offer over the regular tranformer-rectifier-filtering circuit. : r/AskElectronics

what power voltage does this take? : r/AskElectronics

How you I go about switching between either 12vfb or 5vfb, with only one gpio? NFET + PFET? : r/AskElectronics

Is this circuit correct? It's for switching negative voltage on/off with a single transistor and comparator. : r/AskElectronics

Old AT PSU - how to power on? : r/AskElectronics

Simple 400V DC switch : r/AskElectronics

single transistor as a comparator?? : r/AskElectronics

I'm trying to make 2-phase 12V to 20A/5V buck converter on 2 layer PCB. Not sure about laying out copper planes. Should I put ground on bottom layer under inductors? Do I

My MOSFET switch isn't working as expected. I think I am using the wrong type of MOSFET, how do I find the right one for what i need? (aka, how do MOSFETS
