Abstract

The invention discloses a power supply circuit and an electronic device. The power supply circuit comprises a control circuit which is electrically connected with an external power supply; the at least two first voltage conversion circuits are electrically connected with the external power supply and the control circuit and are externally connected with an electrical load; wherein the at least two first voltage conversion circuits are arranged in parallel; each first voltage conversion circuit receives a corresponding first electric signal sent by an external power supply, receives a corresponding first control electric signal sent by the control circuit, outputs a corresponding second electric signal based on the corresponding first electric signal and the corresponding first control electric signal, and outputs the second electric signal to an electrical load; wherein the first control electric signal is also used for adjusting and outputting the second electric signal. According to the power supply circuit provided by the invention, multi-path output of voltage is realized, one path or multi-path output is controlled, the output voltage of each path is adjusted, different power supply requirements of an electrical load in different periods are met, resource waste is reduced, and the power supply efficiency is improved.

Description

technical field [0001] The present application relates to the technical field of power supply, in particular to a power supply circuit and an electronic device. Background technique [0002] With the development of science and technology, the functions of electronic devices are becoming more and more powerful, and their demand for power supply is also increasing. Power supply not only needs power distribution, but also needs to consider efficiency, size, cost and thermal performance, etc. Therefore, the electronic device Power supply is a problem that needs to be studied in depth. [0003] Taking the graphics processing unit (GPU) as an example, with the adoption of AI functions in large-scale learning and inference application deployment, ASICs and GPUs with complex functions are more and more widely used in various industries. The performance of the processor is getting stronger and stronger, and the computing power of the processor is also increasing, so the demand for p...
