Title:
ELECTRONIC APPARATUS AND CONTROL METHOD
Document Type and Number:
Japanese Patent JP2021112095
Kind Code:
A
Abstract:
To enable a desired output voltage to be obtained within an electronic apparatus even when an input voltage from an external apparatus to the electronic apparatus fluctuates.SOLUTION: An electronic apparatus (100) includes power reception means for receiving power from an external apparatus, first voltage conversion means for inputting the power received through the power reception means, generating an output voltage by performing voltage conversion to an input voltage, and generating a predetermined output voltage regardless of fluctuation of the input voltage, second voltage conversion means for inputting the power received by the power reception means, generating an output voltage by performing voltage conversion to the input voltage, and fluctuating the output voltage by the fluctuation of the input voltage, voltage supply means for increasing or decreasing the output voltage and supplying the increased or decreased output voltage to a load circuit of the electronic apparatus, and control means for switching to the first voltage conversion means or the second voltage conversion means based on the voltage supplied to the load circuit of the electronic apparatus, and supplying power to the load circuit of the electronic apparatus.SELECTED DRAWING: Figure 1
