摘要： In an embodiment, set forth by way of example and not limitation a USB power converter for an electronic device includes a USB bus including VBUS power line, a D− data line and a D+ data line, a variable voltage converter, a processor clock, a USB transceiver coupled to the D− data line and the D+ data line, and a processor coupled to processor clock and to the USB transceiver. Preferably, the variable voltage converter has an alternating current (AC) input, a direct current (DC) output coupled to the VBUS power line, and a voltage control input responsive to a voltage control signal to provide a plurality of voltage levels at the DC output. The process is, in this example embodiment, operative to develop the control signal based upon communication from an electronic device connected to the USB bus. In a non-limiting embodiment, the USB power converter further includes a host ID controller having a host ID control input coupled to the processor, the host ID controller selectively coupled to the D− data line and the D+ data line in response to a host ID control signal developed by the processor.
