Hi. Simple question for those that know. I've read that a disadvantage of using switching regulators (vs linear) is the "noise".
Is it rf noise generated by the circuit (that may affect other devices within a certain range)? Or is it "dirty power" that comes out which needs to be cleaned up? Or both, or other?
What I'm wanting to do is provide steady 12v to a camera onboard a radio controlled aircraft. The voltage onboard will start at 12.6v and run down to about 9.9v and I'd like the camera to always see 12v. So I think I'm limited to a buck boost type switching regulator and am just concerned about the noise... what exactly that means and how I may address it.
Thanks.
