What's the best way to provide 48V phantom power for a portable
battery operated microphone device. Obviously a dc-dc convertor of

from scratch I would make an oscillator - step up the voltage then
rectify.

Try it at 9 volts. Most still work fine. I use a Behringer ECM8000
measurement mic at 9v, but the spec says 48v I believe they mean that
to be a maximum.
