Tom, Following on from the switch reg thread of the past few days, most of the chip manufactures (National, SGS, maxim ...) all do step up switching regs. I have just downloaded a bunch of datasheets from National's site at www.national.com, but you could also check out www.st.com (SGS), or www.maxim.com. All of these guys have online datasheets, with application notes. There are a number of DC to DC converter 'modules' on the market too that may well fit the bill.
