Yes. My shielded inductors are larger than the ones in the

I am not sure about this point.
On the NCP1421 layout and the TPS62xxx layout I placed testpoints
so that I could measure the noise without the ground lead on the
probe. The noise was within spec. I also did a min load to max load
test and a max load to min load test and the transients were within
spec.

The picture was just an example, which I found with google. My
DC/DC-Converters are here:

I think your L800 value (0.47u) is incorrect.
