Document Type and Number:
Japanese Patent JP2023096742
Kind Code:
A
Abstract:
To provide a power supply device capable of controlling the power supply device by communication without being impacted by a switching power supply nor sacrificing a characteristic, and capable of subsequently outputting a desired voltage quickly.SOLUTION: A power supply device 1 according to an embodiment of the present invention comprises: switching power supply parts 11 to 14 for switching applied power to an external circuit E1; a control part 2 for controlling the switching power supply parts 11 to 14; a communication part 3 for transmitting/receiving a signal between the control part 2 and an external device M; and an input terminal 4 that accepts an input signal for giving instructions to the control part 2. The switching power supply parts 11 to 14 each comprise: an output circuit which is connected to an output terminal and which perform switching on an output current; and a switching control circuit for controlling the output circuit. The control part 2 is constituted so as to stop switching of the output circuit, while keeping causing the switching control circuit to function in response to the input signal to the input terminal 4.SELECTED DRAWING: Figure 1
