Electricity-saving method and circuit for converting electricity-wasting processor electronic installation into electricity-saving electronic installation

Abstract

The method of converting electronic equipment with non-power economizing processor into power saving one includes the steps of: providing power switch unit and maintaining the on / off state of power switch of the non-power economizing processor in pulse period; generating periodical first pulse signal and second signal for the power saving electronic equipment, cutting off the power supply of the non-power economizing processor with the power switch assembly with the first pulse signal and turning on the power supply of the non-power economizing processor with the power switch assembly with the second pulse signal; and determining the pulse duration of the first pulse signal and that of the second pulse signal to obtain total average current lower than some preset value.

Description

technical field [0001] The invention relates to a power-saving circuit, in particular to an electronic device with a non-power-saving processor, such as a keyboard, a mouse and other input devices, and converts it into a power-saving keyboard, mouse and other input devices. Background technique [0002] Known power-saving technologies applied to processors or controllers, the most common practice is to directly use power-saving processors or power-saving controller components, because power-saving processors or power-saving controllers The cost of the components is high, but this method will cause a large burden on the cost. Another known method is to use a processor or controller with a dual frequency mode, and switch between high frequency and low frequency to supply the processor or controller under a predetermined condition, but the price paid is that both the dual frequency mode must be selected. A working processor or controller. [0003] Due to the requirement of th...

AI Technical Summary

Problems solved by technology

If the above-mentioned first known method is adopted, the manufacturing cost of the USB electronic device cannot be reduced. If the above-mentioned second known method is adopted, the processor or controller manufactured according to this USB IF specification must be used, and it is impossible to adopt Cheaper processors or controllers with dual frequency modes that don't save power, so the overall manufacturing cost will also increase
