I am trying to come up with a simple, yet efficient way to power a nominal 12 volt device (35watts) from a 24 volt battery bank.
This device needs to power the load with 1/2 of the supply voltage, not supply "regulated" 12v output.
It is important that as supply voltage "24v battery" decreases, the output voltage decreases as well.
I have tried a "darlington pair" as well as other transistor based voltage converting circuits, but the waste too much power, dissipated as heat.
Ideas?
