Abstract:
1. A port power switch (PPS) comprising: a first input port configured to receive an input supply voltage derived from a supply voltage generated by a power supply; a first output port configured to provide an output supply voltage based on the input supply voltage, to power a device coupled to a point-of-load (POL); a second input port configured to receive, from the POL, a POL voltage derived from the output supply voltage; a second output port configured to provide a feedback voltage to a feedback port of the power supply wherein the feedback voltage is used by the power supply to regulate the supply voltage generated by the power supply; and a control block configured to switch the feedback voltage provided via the second output port between the first input port and the second input port wherein the control block makes switching determination based on operating conditions of the PPS.
