A power supply circuit of an electrified vehicle according to the present disclosure is mounted on the electrified vehicle including: a battery configured to receive an electric power from an external DC power supply; an accessory configured to operate at a system voltage of the battery; and a DC inlet to which a voltage higher than the system voltage is applied from the external DC power supply. The power supply circuit includes a first power line, a step-down converter and a second power line. The first power line is configured to connect the DC inlet and the battery. The step-down converter is disposed on the first power line and configured to lower a voltage supplied to the battery from the DC inlet. The second power line has one end connected to the first power line between the step-down converter and the battery, and another end connected to the accessory.
