The Cui switchers I recommended have a minimum load current spec of
0.0A, so it won't be a problem. The TU56 will easily present enough load
for any switchers that aren't rated for a LOT of amps. If you try to
use a 5V 100A supply, you may be asking for trouble.

Nothing in the TU56 will be that finicky. The supplies I recommended
are rated at +/- 5% tolerance and will work fine.
