Beschreibung
Zusammenfassung:	In accordance with an embodiment of the present invention, a method of operating a power supply circuit includes receiving an input signal comprising a request for a target power supply voltage and/or current at an interface circuit at a secondary side of an adjustable power supply. The input signal is converted into a digital signal comprising the target power supply voltage and/or current. The digital signal is transmitted via a galavanically isolated signal path to a controller in a primary side of the adjustable power supply.
