Hi All,
I have a project where I need to drive a 12v 0.15A computer fan with a mosfet in addition to a raspberry pi which will control the mosfet with a DAC board.
My initial thought was to get a 12v supply and a buck power converter. Before going to far, I wanted to get an idea of what would happen with respect to noise. Suprisingly, I am seeing massive voltage spikes on my scope when measuring both the 12v and 5v from the buck converter with the fan where I do not see this with an incendecent bulb.
Clearly the fan is pulling back a lot of noise. Is there a simple circuit I can implement to reduce this noise level?
Thanks,
Mark
