Electronic device and control method for the same

A control method that is carried out by an electronic device that includes:

• a first voltage converter circuit that converts an input voltage from a first power source or a second power source to a first output voltage, the first output voltage being 1/n of the input voltage, where n is an integer greater than or equal to 2;
• a second voltage converter circuit that converts the input voltage from the second power source to a second output voltage;
• a third voltage converter circuit that converts a higher one of the first output voltage and the second output voltage to a third output voltage, and supplies the third output voltage to a load;
• and
• the control method comprising:
• in a case where the input voltage from the first power source is to be supplied to the first voltage converter circuit, setting the second output voltage to a first voltage that is higher than a currently set voltage and lower than 1/n of the input voltage from the first power source, and
• after setting the second output voltage to the first voltage, performing control to supply the input voltage from the first power source to the first voltage converter circuit.

A non-transitory computer-readable medium that stores a program that causes, when executed by a computer included in an electronic device to perform a control method,

• wherein the electronic device includes:
