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.
