In a nutshell.. I have a 12V 6A switching power supply feeding a 18" fan @ 13kHz and max 60% duty drawing 4A peak, duty is determined by temperature sensor/arduino/MOSFET using separate power supply at the moment (battery).
My intent is to simplify the power supply by using a buck converter to supply the arduino from the same switching supply as the fan.
Should I expect to fit some filtration before the buck converter ?
