Patent number: 10956350Abstract: The application discloses an electronic device with a USB Type-C connector, which is able to be coupled to another electronic device. The electronic device includes a control unit, a switch unit and a charge conversion unit. The control unit outputs a first control signal according to a result of power supply handshaking between the electronic device and the other electronic device. The state of the first control signal determines whether the other electronic device supplies power to the electronic device. The switch unit is coupled to the control unit, and receives a supply voltage output by the other electronic device, and the switch unit determines whether to output the supply voltage according to the state of the first control signal. The charge conversion unit is coupled to the switch unit. The charge conversion unit converts the supply voltage into a target voltage to supply power to the electronic device.Type: GrantFiled: November 25, 2019Date of Patent: March 23, 2021Assignee: Pegatron CorporationInventor: Chi-Yu Wu
