  • Adaptive overvoltage protection for adaptive power adapters
    Patent number: 10396571
    Abstract: A power adapter includes a protocol integrated circuit (IC) on a secondary side of a transformer and a controller IC on a primary side of the transformer. The power adapter has an output voltage that changes depending on the charging voltage requirement of an electronic device (e.g., mobile device) connected to receive power from the power adapter. The power adapter includes an adaptive overvoltage protection mode that sets an overvoltage protection threshold to a low level during startup and thereafter sets the overvoltage protection threshold to a higher level after detecting proper operation of the protocol IC.
