Dear all: I would like to use an electroluminescent (EL) LCD because it boasts a very low current consumption (~2mA I'm not sure if this is AC). However, its lighting power source requires AC100Vrms, 400Hz. The application that I'm working on can only use a 9V battery and a 5V regulator. 1) Is there some IC that can convert DC5V into AC100Vrms, 400Hz? 2) The current probably will not be DC2mA will it? If not, what might it be? Thanks in advance.
