  • Power supply
    Patent number: 10466755
    Abstract: A power control device includes a memory device and a resistor coupled to the memory device. The memory device includes a first memory block storing a plurality of groups of performance parameters and a second memory block storing a power supply program. A resistance of the resistor corresponds to one of the groups of performance parameters. The power control device is configured to control power supply to an electronic device coupled to the power control device according to the power supply program and the one of the groups of performance parameters corresponding to the resistance of the resistor.
