If you need more than 100 ma then use two in parallel with each operating at even less than 50% derate? For voltages over 390 then two in series dialed into the needed voltage. So easy, and small, and inexpensive, and variable. But Noise might be the price you pay for such convenience. If the noise can be filtered out, to be imperceptible in a blind comparison to a good linear regulated supply, that's great.
I can see a preamp with one of these and a meanwell EPS open frame card at 15 volt 10 amps supplying a linear DC filament supply and this booster simultaneously. Two little cards, under 8 ounces and a few square inches for the whole PS.
