These are cheap at 1.20ea including shipping.
Needs a small inductor for use, but the inductors
are readily available and they are also pretty cheap.
I think you could also wind your own torroids for
these easily.
The 3amp rating would be good for a prop project
that needs a lot of current. Should work much like
a standard to220 3v3 regulator except 3x the current
and much more efficient and no need for an input V
close to 3.3v ... I guess they would be ok even with
something like 12-15v or even more.
I'm going to try these, will post how it goes after
they are delivered
