Default HV Bias Supply Challenge

OK, here's a challenge to you guys ... I have been trying to ID a IC /
inductor combination to generate 150 to 200 VDC ... in the nano-microamp
range. I need to supply a bias voltage to an electrostatic microphone
element.

Any ideas ??

Wish list:

Very low current ... 2ma ;-)
Runs from 5 to 9 volt DC source
Minimal components

Most of the specs I find for HV units ( backlight supplies ) are too much
current. Most of the inductor type DC-DC converters seem geared towards low
voltage high current apps.

Will watch the discussion for tips and ideas ... all welcome.

Thanks

Tony, KD7TOG
