Yes.. the BEST thing is the LTC1044ACN8 (for voltages up to 12 or 15
volts i think) OR the LTC1044CN8 (for voltages up to 9v)
These things can easily invert any voltage and do so with very low
ripple..I burned one of these up in a piece of gear the other day
(Syntecno TeeBee) and was amazed that all that was being done with just
Im sold on them.. i went out and bought 5 of em cuz I know of a billion
Linear Technologies has the data sheets on the web site.
