I plan to build a circuit that is able to output 3.2 to 9 volts of power, to a load of 1.1 to 5 Ohms (depending on a few outside factors). Battery around 3.7 volts
Originally I was looking for a DC / DC step up (boost) regulator. I found plenty that were capapable of boosting adjustable voltage to my requirements with pretty simple schematics. But if the load is 1.1 Ohms, it would be drawing up to 8.1 Amps of current (at 9 Volts) correct? I cannot find a boosting regulator / controller that can handle that load.
So unless I'm looking at things wrong, I may be looking at a higher voltage battery, and some sort of step down regulator. From average specs I've seen so far, they can handle higher current draw.
Does anybody have any suggestions? In the end, I just want an adjustable voltage powersupply, from 3.2 to 9 volts, to drive a load of 1.1 Ohms. As small as possible, with simple wiring. If you can't tell, I'm very new to all this, but i'm trying to self teach, lol
