Abstract

Dynamic power throttling based on system conditions in a USB Type-C power delivery ecosystem is disclosed, describing techniques for dynamically throttling power in a power delivery system. In one embodiment, the power delivery system includes a controller associated with a port for supplying power. The controller manages a power budget available to the port based on a current state of one or more system parameters. The power budget available to the port can be throttled when the power delivery system is operating under a stress condition, and the power budget available to the port can be adjusted when the power delivery system is no longer operating under the stress condition.
