I bought a couple of 5 pins step up, and i don't need with the circuit, easy enough i just can't get my head around it.
I can understand how step down works, eg, take 15volts, oscillate at a high frequency and reduce the voltage coming out and smooth it through a cap....
but going up? All i can imagine is thousands of capacitors or inductors with diodes all aligned to give say 35vdc from 3vdc, and then switch it at high frequency to get the desired voltage out?...
chances are as usual, i'm probably way off lol
