I little series L and another C (so you have a pi low pass) can make a
huge difference. If the load current is reasonably constant, then the
drop across the series R of the L will be constant, so you can bump the
dc/dc output to compensate. It's pretty easy to get 60dB of rejection
from a C-L-C pi, and for 2MHz, the parts are physically small.
Wouldn't it be better to use a ferrite bead instead, for this application?
The much lower series capacitance and thus higher self-resonance frequency
should help damping the spurs.
sure, if you can get enough L. The other thing is that SMD inductors
can be placed by machine, which isn't necessarily the case with ferrite
beads (depending on how you do them).
