Hello,
keeping in mind the application of the ADP230X, in a non inverting configuration, to obatin -14.5 V from a +5 V power supply, the maximum operating voltage of 20 V is closer near and considering some tolerance of the input voltage this limit can be reached .The ADP230X has an overvoltage protection that will prevent the part.
It is safe to operate the ADP230X near the 20 V, or it is better to select other part for the this application?
Regards,
Oscar
