I have a simple PWM circuit with a NPN transistor driving a DC fan. Exactly like in the attached schematic. The issue is I'm getting serious voltage spikes on the 5v.
This is by design, right? The flyback diode sends the current back to the 5v source?
The problem is I have other things in the circuit that get their power from the same 5v, and are not liking the voltage spike. Any ideas how to fix this?
