I have built the typical applicaiton circuit from teh MIC4830 datasheet. I have used the values for 0.4inch2 EL panel running at 900Hz (REL=0.369MOhm, RSW=321kOhm). The input voltage is 3.3V My problem is that the output voltage is around 40Vpeak-to-peak. I have checked all pins with an oscilloscope, the waveforms seem to be OK, switching frequencies are very close to the required values. I don't seem to find what could be wrong. Any ideas why am I getting a too low output voltage?
Thanks.
Thanks.
