You are looking for a DC-DC converter. Specifically, you are most
looking for a "Boost converter." (There are also "Buck converters" for
stepping down voltage, and "Buck-Boost converters" that can do either).

Surprizingly, there is a decent overview on Wikipedia:
http://en.wikipedia.org/wiki/Boost_converter
http://en.wikipedia.org/wiki/Buck-boost_converter

That (and a couple of distributors) should get you started. Good luck!
