Abstract
A voltage control system is configured with a constant voltage circuit, a semiconductor package and a power supply package. A power supply chip of the power supply package is configured to control the constant voltage circuit based on an input voltage supplied to the semiconductor package and an operating voltage of a semiconductor device so that the input voltage decreases as the voltage difference between the input voltage and the operating voltage increases.
Claims6
A voltage control system comprising:
- a constant voltage circuit;
- a semiconductor package, in which a semiconductor chip including a semiconductor device is integrated;
- and
- a voltage control circuit configured to control the constant voltage circuit based on an input voltage, which is supplied from the constant voltage circuit to the semiconductor package, and an operating voltage of the semiconductor device, which corresponds to a leak current and an operating current of the semiconductor package,
- wherein the voltage control circuit is configured such that the input voltage supplied from the constant voltage circuit to the semiconductor package is decreased as a voltage difference between the input voltage and the operating voltage increases.
