Just when I thought I had everything covered, something new comes up.

I've got some PIC based devices, with a built in small linear supply.  I use
a 220/110 input transformer, and up to now have always had either voltage
available.  Or could figure out a way to get it.

But now a client has 380VAC 3 phase, and demands (I hate that!) to use only
220VAC single phase for all control voltages.

I can find sources on 380 to 110 transformers, but can't seem to locate
anything that will take 380 to 220, in either a control or buck-boost.  All
I need is about 250VA.

And I cannot do this in a custom, the quantities don't warrant the expense
on that.

Anyone know of a vendor that has this in the standard line-up?
