Abstract

Official abstract text for this publication.

Power converters are provided that convert alternating current (AC) power to direct current (DC) power. A power converter may have multiple ports. Each port may have an associated connector with multiple power and data terminals. When an electronic device is connected to a given port, the electronic device draws DC power from the power converter. To ensure that the capacity of the power converter is not exceeded when multiple devices are connected to the ports of the power converter, the power converter may actively monitor its ports for active loads. Load detection circuitry can determine what number of ports are active. Control circuitry can compute a per-port available DC power level based on the number of active ports and can provide this information to connected devices.

First claim

Opening claim text (preview).

What is claimed is: 1. An apparatus configured to provide power and power level data for a plurality of external electronic devices, the apparatus comprising: a plurality of ports; load detection circuitry that detects when at least one of the plurality of external electronic devices is connected to the apparatus, wherein the load detection circuitry comprises a control switch and a current-limited voltage regulator configured to provide an output voltage larger than a nominal…
