Abstract
The present disclosure provides various embodiments of an external power supply and methods to enhance the output power delivered by an external power supply to a power consuming load. As described in more detail below, the embodiments disclosed herein enable an external power supply to deliver a higher than maximum output power for short periods of time when ambient temperatures within the external power supply are low. As the ambient temperature increases, the embodiments disclosed herein throttle (or incrementally reduce) the output power delivered by the external power supply until the maximum output power specified for the power supply is reached. Although not strictly limited to such, the external power supply may be a Universal Serial Bus (USB)-enabled AC/DC adapter, and more specifically, a USB Power Deliver (USB-PD) AC/DC adapter, in some embodiments.
