Ok so I'm looking to provide temp. regulation to a TEC, I have a digital fan controller that will vary the voltage to a fan (max 1A) basied on temp. I'd like to use the same controller to run my TEC but I need about 14A for it at max power. as I under stand things I should be able to use a Transistor ,or even a few, to do this but I don't really know how to set it up? the controller I have varies the voltage from 3.7v to 12v (or power supply rail voltage).
altertively I could use a PWM if there is one that will act basied on the controllers output voltage if there is something like that availabe out there.
I can read and convert scematics to pcb layout and physicly build this, but my electronics experiance is mostly in repair not in design...
Thanx ya'll
