POWER EXTENDING BOARD AND POWER SUPPLY SYSTEM AND ELECTRONIC DEVICE USING SAME

摘要

An exemplary electronic device includes a mother board, a power source, and a power extending board detachably connected between the power source and the motherboard. The power source includes a golden finger interface. The power extending board includes a receiving socket, a first conversion circuit, and a first connector. The golden finger interface is plugged into the receiving socket. The first conversion circuit is connected to the receiving socket, converts first and second voltages from the power source into third and fourth voltages, and outputs the first, third, and fourth voltages to the motherboard.

主权项

1. A power extending board, configured to transfer a first voltage and a second voltage from a power source comprising a golden finger interface to a motherboard of an electronic device, the power extending board comprising:
a substrate; a receiving socket positioned on the substrate and detachably connected to the golden finger interface of the power source; a first conversion circuit positioned on the substrate and connected to the receiving socket; the first conversion circuit receiving the first voltage and the second voltage from the power source via the golden finger interface and the receiving socket, converting the first voltage into a third voltage, converting the second voltage into a fourth voltage; and a first connector positioned on the substrate, the first connector comprising three first conductive pins, a first end of each of the three first conductive pins connected to the first conversion circuit, and a second end of each of the three first conductive pins being detachably connected to the motherboard of the electronic device, the three first conductive pins receiving the first, third, and fourth voltages respectively, and outputting the first, third, and fourth voltages to the motherboard.
