'[EE]: EL backlight circuit'

On a similar note to the CCFL post has anybody got a URL for an EL backlight
circuit.

I think I've worked out that I need about 120V (AC ?) from an inverter unit
to supply a EL sheet of approximate size 100mm*80mm.

The inverter can run from 5v->20V and to get about 120->150V out of it I
need about a 12V input supply.

Now do I just buy one of these inverters, give it 12V and connect the 120V
output to the EL?

I'm a bit worried of the 120V (large number!), I guess it's very low
current. Why such large voltages?

So a URL or a circuit idea would be great.

Also they seem to be big devices and I'm trying to design a ultra slim
control panel. Are there such things as SMD (surface mount) inverters?

Regards

Pete

look under "literature" for data sheets, design guideline for inverters,
etc.
(anything remotely technical)

Rohm and Sipex make single-chip EL inverters
