Abstract
Systems and methods of interconnecting devices may include an input/output (IO) connector having a buffer with an integrated voltage regulator. The integrated voltage regulator may include a first supply output and a second supply output, wherein the IO connector includes an IO power contact coupled to the first supply output. The IO connector may also include a logic power contact coupled to the second supply output. In one example, a host device may issue power management commands to the buffer in order to scale the second supply output independently of the first supply output.
Claims24
A system comprising:
- a local host device;
- and
- an input/output (IO) connector including a buffer that is to detect a connection of a peripheral device that is external to the local host device to the IO connector, an IO power contact and a logic power contact, the buffer having an integrated voltage regulator coupled to the IO power contact and the logic power contact, wherein both the IO power contact and the logic power contact are to provide connection to the peripheral device, wherein the IO power contact is to supply power to a signaling circuit on the peripheral device, and wherein power supplied at the logic power contact is adjustable independently of power supplied to the signaling circuit, wherein the local host device is to conduct a power management analysis to determine an amount of power on the local host device that is available to be provided to the peripheral device,
- wherein the buffer is to disable a supply output of the integrated voltage regulator to at least one of the IO power contact and the logic power contact if the peripheral device is an external host device, and
- wherein the IO connector is to adjust the supply output to at least one of the IO power contact and the logic power contact based on the power management analysis.
