So I've got an EL driver that I want to use for a wearable, but it's=20
bulky for that purpose, and I need something very thin.  Seems the=20
battery and transformer are the larger parts of the whole driver=20
module.  I decided to redesign it with a LiPo, but it seems that all the=20
EL driver circuits I'm finding have transformers.  The EL-wire spec is=20
90-120V at 1Khz-2kHz.  Couldn't I use a high-voltage LED driver for this=20
purpose?  Something like Fig 8 here...

I'd still have to throw an oscillator in there to modulate the LED=20
driver, so I'll have to experiment to see if the LED driver can switch=20
on/off that quickly.

Anyone know of a simpler way to do this?  Or maybe even a very thin (say=20
few mm tall) transformer that can work for this purpose?

Cheers,
-Neil.
