Abstract
A power supply circuit includes a first power supply line that couples a first input node from which first input power is input and an output node to each other, a second power supply line that couples a second input node from which second input power is input and the output node to each other, a power limit of the second input power being higher than that of the first input power, a converter that is inserted in the first power supply line and that converts a voltage of the first input power input from the first input node to a higher voltage or a lower voltage, an adjustment circuit that adjusts an output voltage of the converter to a voltage higher than a voltage of the second input power input from the second input node.
