Abstract

The invention provides a transient current outer loop and a design method of the transient current outer loop, which are used for an electronic device. The electronic device comprises a power supply circuit and a plurality of hardware, wherein the power supply circuit is used for supplying electricity energy to the hardware; the transient current outer loop comprises an energy storage module and a power supply compensation module; the power supply compensation module is connected with the energy storage module and charges the energy storage module with electricity. When any one of the hardware is started up, the power supply compensation module compensates the electricity energy in starting of the hardware via releasing the electricity energy of the energy storage module, and thus, the electronic device does not need to configure a corresponding compensation module for each hardware, so that the configuration area of the power supply circuit can be reduced and the use of parts is reduced.

Description

technical field

[0001] The invention relates to a power supply circuit of an electronic device, in particular to an instantaneous current supplementary circuit for an electronic device and a design method thereof. Background technique

[0002] As the hardware requirements and functions of electronic devices increase, the output requirements of power circuits also increase correspondingly, for example, the establishment of hardware such as WiFi, WAN, GPS, NFC and other communication chips or modules. These hardwares usually do not work at the same time, and these hardwares have different levels of withstand voltage, load current and maintenance time at the moment of startup. Therefore, any hardware usually makes the power supply circuit supply power in This instantaneous unbalance phenomenon occurs, therefore, it is necessary to provide corresponding current supplementary circuits for different hardware, so that these hardware can maintain the voltage level within the normal ...
