Low impedance power supply circuit and electronic device

Abstract

The present disclosure relates to a low-impedance power supply circuit and an electronic device, the low-impedance power supply circuit comprising: a voltage regulation module comprising an inductor, the inductor being mounted on a PCB surface, and an output end of the inductor being coupled to a power load as an output end of the voltage regulation module through a power supply layer in the PCB, wherein the power load is mounted on the PCB surface; a conductive strip being located outside the PCB, and one end of the conductive strip being coupled to the output end of the inductor, and the other end of the conductive strip being coupled to the power supply layer through a via hole. The present disclosure widens the cross section of the power supply current and the width of the current path by adding the conductive strip between the voltage regulation module and the power load, which helps to reduce the line impedance from the voltage regulation module to the power load, and further helps to reduce the power loss and improve the power efficiency.
