Voltage regulating device for dynamically regulating voltage in a computer system

摘要

The invention provides a voltage regulating device for regulating the operating voltage of a CPU in a computer system. The voltage regulating device includes a voltage identification signal regulator and a voltage identification signal bridge. The voltage identification signal regulator is controlled by a controlling signal to output a voltage identification regulating signal to the voltage converter. In this case, the voltage converter outputs the operating voltage of the CPU according to the voltage identification regulating signal. Meanwhile, a voltage monitor is used to monitor the operating voltage. When the voltage identification signal regulator outputs the voltage identification regulating signal, a voltage identification signal bridge blocks a default voltage identification signal output from the voltage identification signal setting device.
