[0002] With the booming development of the semiconductor industry, various semiconductor manufacturers have launched a variety of products. However, the power supply standards of these products are not consistent, which requires users to provide multiple supply voltages to meet their products when using these products. This means that users must convert the input voltage into the voltage required by their products through a voltage converter in the current system. When the system is in standby, these voltage converters also need to be in a working state to maintain the power supply of the minimum system of the circuit. However, the voltage converter itself also consumes power during the voltage conversion process, and there are conversion efficiency problems in the voltage conversion, which will also cause power consumption during the conversion process. For devices powered by batteries, the power consumed over a long time is also very large, which is not conducive to the long-term operation of the product and the miniaturization of the device.

[0003] Therefore, how to reduce the standby power consumption of the system is a technical problem that needs to be solved urgently at present. Summary of the Invention

[0027] The exemplary embodiments of the present invention will be described in more detail below with reference to the drawings. Although the exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present invention can be more thoroughly understood and the scope of the present invention can be fully conveyed to those skilled in the art.

[0028] Embodiment 1:

[0029] An embodiment of the present invention provides a method for reducing the standby power consumption of a system, which is applied to a battery-powered system, such asFigure 1 As shown, the battery-powered system includes: a battery power source 101, a power switch 102, a voltage conversion module 103, a processor 104, and a peripheral device 105 connected in sequence. The power supply system further includes: a power supply interface between the voltage conversion module 103 and the processor 104, and a super capacitor 106 is connected between the power supply interfaces. As Figure 2 shown, the method includes:

[0030] S201. During normal operation, the battery power source 101 supplies power to the processor 104 through the power switch 102 and the voltage conversion module 103, and the battery power source 101 charges the super capacitor 106;

[0031] S202. In the standby state, the processor 104 controls to turn off the peripheral device 105 and controls to disconnect the power switch 102, so that the super capacitor 106 supplies power to the processor.

[0032] In a specific embodiment, according to different processor models or specific functions, the processor 104 may have multiple voltage input interfaces, and there is a power supply interface corresponding to each voltage input interface, and a super capacitor 106 is provided at each power supply interface. For example, the supply voltage of some voltage input interfaces is 3.3V, and the supply voltage of some voltage input interfaces is 1.5V, which is not limited herein.

[0033] As Figure 3 shown, when the processor has multiple voltage input interfaces, there is a corresponding voltage conversion module for each voltage input interface. That is, when the battery power source 101 supplies power through the power switch 102, it can be converted into different voltages by different voltage conversion modules for the processor 104 to use.

[0034] First, during normal operation, that is, when the battery power source 101 supplies power, the battery power source supplies power to the processor 104 through the power switch 102 and the voltage conversion module 103. Since the power supply interface between the voltage conversion module 103 and the processor 104 is connected to the super capacitor 106, the super capacitor 106 is charged under normal power supply conditions.

[0035] In the standby state, the processor 104 controls to turn off the peripheral device 105 and controls to disconnect the power switch 102. At this time, the battery power source 101 does not consume electrical energy, and the super capacitor 106 charges the processor 104.

[0036] Specifically, the power consumption of the processor 104 in the standby state is very low, and the electric energy stored in the super capacitor 106 is sufficient for the processor 104 to work in the standby state.

[0037] When the device switches from the standby state to the normal state, there are two specific methods, one is the peripheral wake-up method, and the other is the internal wake-up method of the processor 104.

[0038] Specifically, when the processor 104 receives a peripheral wake-up signal, it controls the power switch 102 to turn on, so that the battery power supply 101 supplies power to the processor 104 through the power switch 102 and the voltage conversion module 103.

[0039] In another case, when the processor 104 receives an internal wake-up signal, it controls the power switch 102 to turn on, so that the battery power supply 101 supplies power to the processor 104 through the power switch 102 and the voltage conversion module 103.

[0040] Regardless of which wake-up method is used, the device can be switched from the standby state to the normal mode.

The battery-powered system further includes: a power supply interface between the voltage conversion module and the processor, and a super capacitor is connected between the power supply interfaces. The method includes: when working normally, the battery power supply supplies power to the processor through the power switch and the voltage conversion module, and the battery power supply charges the super capacitor; in the standby state, the processor controls to turn off the peripheral and controls to disconnect the power switch, so that the super capacitor supplies power to the processor, and further cuts off the power supply of the battery power supply in the standby state, so that the super capacitor supplies power to the processor, thereby reducing the power consumption.
