Abstract
In a power supply apparatus for supplying a target power supply voltage to a microprocessor, a system controller sets the target power supply voltage to be supplied to the microprocessor based on a voltage configuration signal outputted from the microprocessor and outputs a voltage setting signal corresponding to the target power supply voltage. The regulator circuit generates the target power supply voltage set by the system controller based on the voltage setting signal outputted from the system controller and supplies the voltage to the microprocessor. The system controller acquires the conditions of the microprocessor, such as the operating time and temperature of the microprocessor and the amount of computation in the microprocessor, and reflects the acquired conditions on the setting of the power supply voltage.
