Hi,
I'm trying to create a cooler curcuit using a couple of peltiers and a CPU cooling setup. It's for a meter cubed temperature controlled environment, not a PC.
I have a confirmation question about increasing the current in the curcuit for the peltiers that require 9A at 12V. My supply will go from 3 to 24V and I'm not sure if the 200mA is constant across all voltage values.
I have made an educated guess that if I want 9A for the peltiers, it has to be in the curcuit to start with and the 200mA will not be able to be magically amplified but I'd like confirmation. I was reading up on a Darlington Pair, but I think that this is more for switching amps than creating them.
Cheers
Si
