Abstract

The invention relates to a power supply circuit and an electronic device. The power supply circuit comprises N power supply modules, N first switch modules and a first capacitor module, and the powersupply modules are used for providing power supply signals. The first end of each first switch module is correspondingly connected with one power supply module. The first end of the first capacitor module is connected with the second ends of the N switch modules, and the second end of the first capacitor module is grounded, wherein N is an integer greater than or equal to 2. The first switch module is conducted in response to the first control signal, to transmit the power signal of the corresponding power module to the first end of the first capacitor module, and the first switch module is turned off in response to the second control signal to isolate the corresponding power module from the first capacitor module, so that the wiring space on the mainboard of the electronic device can be saved.

Description

technical field [0001] The present disclosure relates to the technical field of electronic equipment, in particular, to a power supply circuit and electronic equipment. Background technique [0002] With the development and progress of technology, the volume of electronic equipment tends to be miniaturized. Based on the miniaturization trend of electronic equipment, the space inside the electronic equipment is also limited, for example, the space on the motherboard of the electronic equipment is limited. However, the functional requirements of electronic devices are becoming more and more diverse, and more devices are usually required to realize the diversified functions, which makes it difficult to arrange devices on the limited space of the mainboard of the electronic device. Contents of the invention [0003] The purpose of the present disclosure is to provide a power supply circuit and electronic equipment, and further overcome the problem of difficulty in arranging co...
