DC - DC converter

[anechoic]

just wanted to share a great part by V-Infinity

I am using it in a microphone preamp with two 9v batteries in parallel
fed into the D5-D15
and spits out ±15v
the nice thing is that it needs a minimum of parts to work
a large electro cap and a 100µH choke on the input
and the usual filtering caps on the output
its all in the spec sheet/an
caveat: the V-Infinity tech spec for these DC converters is inaccurate and badly needs to be updated...at least they needed to be as of June 2007
but I soldered up the part today and it works wonderfully
