Are there convenient and inexpensive ICs or modules that will convert 3 VDC or 6 VDC from a battery pack to +/- 15 VDC and a ground? Can you recommend a part?

I want to drive maybe a half dozen op-amps and one wife, so I suppose around one or two hundred mA. I don't actually have a good feel for the current requirements, but some basic amplifying and filtering stages.

The current requirements for a wife are around USD 50 000 per annum, I believe. (;-)

All commentary aside as to whether or not Maxim actually exists, I've used their MAX742 to turn 5V into +/-12 fairly successfully before. They say it can also be used to give +/-15, but I can't swear to it.

Strike that, I used the MAX743. Internal FETs instead of external.

The little dc-dc bricks (Mouser, Digikey) are hard to beat unless your volume is huge.
Wives are never to be beaten, regardless of your volume.

In case anyone was wondering, I really did want to convert 3 or 6 VDC to

Vin = 4.2 to 6 V, Vout = +/- 15V or 12 V. That looks like just thing for me. Price @1k $4.49. I don't need that many, but I have a part number now. Thanks.
