I hope I'm using the right board for this....
I am playing around with a NGW100 board and a LCD. I am trying to figure out what backlight inverter to use. Can anyone recommend me an inverter I could buy? I don't really know what a backlight inverter is or what it does and I am hoping I can find one on sparkfun if it goes by another name.

The LCD I am using is a TX14D12VM1CBB. The specs for the backlight are:
Lamp Volatage: 760 Vrms (??)
Frequency: 55 kHz
Lamp Current: min:2, Type:5, Max:6 mA
Static Discharge Voltage: min: 1300 Vrms

I got that from the spreadsheet:

Hi,
This should work, assuming you have a 5V supply. Variants for 3.3V are also available. Frequency is not very critical, nor is output voltage. But that 760V is real, not a typo...
Another I found is BXA-502 from JKL components. Both at Mouser or DigiKey.
Hope this helps,

Great thanks!
so both parts output 650V (for the BXA-502) or 750V, this is still going to work even though I need 760? I'm guessing it's only going to affect light intensity, am I right?

[elevator4]

exactly, and if you're lucky there might even be a pot to set the voltage.
But be careful, 750V is a lot of volts

Will do.

Thanks a lot.
