we have few designs based on LT8471 which are creating noise in the analog cards whom they are powering
to avoid this we have incorporated local LDO with output pi filters after the DC-DC
but still we see few problems of noise at the Op-Amp input stages
can you please help us in how to perform noise analysis of switching supplies using LTspice ?
I want to experiment with multiple pi filters and varied load conditions, kindly help
