Power Supply Apparatus with System Controller
First Claim
1. A power supply apparatus for supplying a power supply voltage to a microprocessor, comprising:
- a system controller which sets a 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 set target power supply voltage; and
a regulator circuit which 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 target power supply voltage to the microprocessor, whereinthe system controller acquires an operating time of the microprocessor and reflects the obtained time on the setting of the target power supply voltage.

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 10. 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.
