  • Current sharing for multi-output charging device
    Patent number: 12244169
    Abstract: A charging device, comprising a first power converter configured to provide a first output current, a second power converter configured to provide a second output current, a switch coupled to an output of the first power converter and an output of the second power converter, a first socket coupled to the output of the first power converter, a second socket coupled to the output of the second power converter, and a power delivery (PD) controller configured to control a turn ON of the switch in response to a coupling of the first socket to a first powered device and an absence of coupling of the second socket to a second powered device.
    Type: Grant
    Filed: September 20, 2023
    Date of Patent: March 4, 2025
    Assignee: POWER INTEGRATIONS, INC.

  • Current sharing for multi-output charging device
    Patent number: 11799311
    Abstract: A charging device comprising a first power converter configured to provide a first output power, a second power converter configured to provide a second output power. A switch is coupled to the first power converter and the second power converter. A first socket is configured to deliver the first output power from the first power converter to a first powered device. A second socket is configured to deliver the second output power from the second power converter to a second powered device. A power delivery (PD) controller configured to detect a coupling of the first socket to the first powered device. In addition, the PD controller is configured to detect an absence of coupling of the second socket to the second powered device. Furthermore, the PD controller is configured to control the switch to provide the first output power and the second output power to the first powered device.
