Abstract
A power management circuit includes a voltage sensing circuit and a supply voltage adjusting circuit. The voltage sensing circuit is arranged for sensing a plurality of voltages respectively of a plurality of nodes of a PCB to generate a sensing result. The supply voltage adjusting circuit is coupled to the voltage sensing circuit, and is arranged for determining a voltage level of a supply voltage supplied to a power plane of the PCB by referring to the sensing result.
