Abstract
A power adapter and method of use wherein a power adapter provided with a power supply portion and human detection and cooling circuitry may be cooled and/or disabled upon detection of a human proximate the power adapter. In use, a voltage regulator integrated circuit of the power adapter is disabled if an overload temperature is sensed. Alternatively, if a human presence is sensed proximate the power adapter, the voltage regulator integrated circuit is also disabled and a cooling fan is energized.
Claims19
A power adapter, comprising:
- a power supply portion coupled to human detection and cooling circuitry via an enable/disable input of a voltage regulator integrated circuit of the power supply portion;
- the voltage regulator integrated circuit provided with a temperature sensor;
- and
- the human detection and cooling circuitry provided with a sensor;
- the human detection and cooling circuitry configured to disable the voltage regulator and energize a fan of the human detection and cooling circuitry upon detection of a human presence by the sensor.
