Abstract
A bidirectional direct current (DC)-DC converter circuit and an electronic device, relating to the technical field of power supplies. The bidirectional DC-DC converter circuit is connected to an energy storage circuit (90), and the energy storage circuit (90) performs charging on the basis of a power supply DC or is used for outputting a battery voltage for power supply; the bidirectional DC-DC converter circuit comprises a control circuit (01), a first switch circuit (02), and a voltage transformation circuit (03); the control circuit is connected to a configuration channel signal, outputs a first switch signal in response to the configuration channel signal being at a first level, or outputs an enable signal in response to the configuration channel signal being at a second level; the first switch circuit is connected to the power supply DC-DC converter, and transmits the power supply DC-DC converter to the energy storage circuit on the basis of the first switch signal; and the voltage transformation circuit converts the battery voltage on the basis of the enable signal to output a power supply voltage. In this way, the use convenience of the bidirectional DC-DC converter circuit is improved.
