Slightly misbehaving switcher (from SED discussion)
Hello Joerg,
[DSP DLL losing lock with small output caps...]

This is not good at all. Something on that DSP seems to be quite marginal if
a wee ripple can knock it off the rocker.
Yeah, I certainly agree. It deserves closer examination, although it wasn't
part of the overall circuit I was involved in and hence thus far I've just
been adding bigger caps when asked to do so. :-) I'll mention your comments
to the guy who did the DSP circuitry... we probably should at least stand over
the PCB and key up a 5W HT and see whether or not the board explodes...
