Abstract

A computer system includes a computer system unit and a power supply circuit. The power supply circuit is coupled to receive input power and generate output power. This circuit includes a circuit to generate a control signal that is related to the power level of the input power. The control signal has a first value relative to the input signal if the input signal exceeds a selected threshold level and the control signal has a second value relative to the input signal if the input signal does not exceed the selective threshold value. The power level of the output power is controlled so that it does not exceed a maximum power level which is based on the level of the control signal.
