  • USB device and operation method thereof
    Patent number: 11119550
    Abstract: A USB device and an operation method thereof are provided. The USB device includes a first switch, a second switch, a power converter, and a first USB connector. A first terminal of the first switch is configured to receive a first voltage. The power converter is configured to provide a second voltage, and the second voltage is less than the first voltage. A first terminal of the second switch is coupled to the power converter to receive the second voltage. A first power pin of the first USB connector is coupled to a second terminal of the first switch and a second terminal of the second switch.

  • POWER SUPPLY DEVICE AND POWER SUPPLY METHOD
    Publication number: 20210203171
    Abstract: The present disclosure relates to a power supply device including a voltage conversion circuit, a switching circuit and a control circuit. The voltage conversion circuit is configured to generate a charging signal according to the power supply signal. The switching circuit is electrically connected to the voltage conversion circuit, and is configured to selectively conduct the voltage conversion circuit to a first device or a second device. The control circuit is configured to the switching circuit. When the voltage conversion circuit charges the first device and the charging signal corresponds to a first switching condition, the control circuit controls the switching circuit to disconnect to the voltage conversion circuit and the first device, then controls the switching circuit to connect to the voltage conversion circuit and the second device to charge the second device.
