Optional: Reverse Voltage Protection Circuit with a N-Channel MOSFET
I recommend to use a heat sink if more than 7A input current is used over a longer period of time. I am using an IRF3205 mounted on a PCB and it is installed below the fan, doing 10A below 100°C.
Optional: Output switch
Since the converter does not fully turn off, I installed a relay on the output using the red LED to turn it on as soon as the converter is active.
