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?

How much current do you want, and how many wives?

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. (;-)

The good news is that nothing is compulsory.
The bad news is that everything is prohibited.

In case anyone was wondering, I really did want to convert 3 or 6 VDC to
+/- 15 VDC.

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.

MAX743, found on a Google sponsored link,

http://www.maxim-ic.com/quick_view2.cfm/qv_pk/1344

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.

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.
