Three-terminal switcher modules intended to replace three-terminal
regulators are fairly expensive, around $11 and up in small quantities.
Digikey has some made by TI, page 416 of catalog T023 (Sept-Dec 2002).

If anyone wants an isolated 5V to 9V converter, I've got a huge pile
of them. I use them with a 7805 to get an isolated 5V supply.
