Zusammenfassung:	A power supply 105 includes a connector 235, a power conversion controller 215 to generate a power supply signal at the connector, and a communication and control processor 240. The communication and control processor is to receive a set of current control parameters including a current limit over a communication link 260 in the connector, receive measurements of current and voltage of the power supply signal, and generate a drive signal for controlling the power conversion controller based on the received current control parameters and the measurements of the current and the voltage. The power supply may further comprise a power transistor 220 coupled to an input power terminal, a transformer 225 coupled between the power transistor and the connector, where the power conversion controller control a duty cycle of the power transistor for storing power in the transformer to generate the power supply signal, and a current sensor coupled to the transformer and the communication and control processor to measure the current of the power supply signal.
