Title: DC-DC CONVERTER AND MULTI-OPERATING MODE IMPLEMENTATION METHOD THEREFOR
Abstract:
A DC-DC converter and a multi-operating mode implementation method therefor, the method comprising: detecting voltages of an input terminal (301) and an output terminal (302) of a DC-DC converter, and generating an operation mode control signal according to the detection result (S101); according to the operation mode control signal, controlling the statuses of a forward switch circuit (303) and a reverse switch circuit (304) (S102); the forward switch circuit (303) and the reverse switch circuit (304) are arranged in parallel connection between the input terminal (301) and the output terminal (302) of the DC-DC converter. The present invention enables two-way conduction of the DC-DC converter, thus facilitating the miniaturization of a product.
