xristost Posted February 24, 2012 Report Share Posted February 24, 2012 I know. I do not really need more than 20 volts, so I think a 24 volt charger fits my needs, could use this design with the charger I mentioned earlier?Part of the circuit will not work, because it use AC voltage to make negative supply voltage for U3. But charger will provide only DC voltage. Quote Link to comment Share on other sites More sharing options...
