Circuit and method for regulating portable device work efficiency according to power converter specification

Abstract

This invention relates to a circuit and a method for regulating working efficiency of a portable device in terms of supply converter specifications, in which, the voltage of its detection supply converter is corresponding to the output of a supply converter, the voltage of which is compared with a threshold value corresponding to the specification of the supply converter to generate a low potential signal to adjust the working efficiency of the portable device based on the signal or generate an identifying signal based on the specification so as to further adjust the working efficiency of the device.

Description

technical field [0001] The present invention relates to a circuit and method for adjusting portable devices, in particular to a circuit and method for adjusting working performance of portable devices according to power converter specifications. Background technique [0002] By the way, today's technology is getting more and more advanced, and semiconductor technology has entered the nanometer era, making today's technology products all require lightness and shortness. Therefore, today's industry has developed various portable devices, so that people who often need to go out You can also enjoy the convenience brought by technology when you go out, such as notebook computers and personal digital assistants (Personal Digital Assistant, PDA), which are not only easy to carry, but also can be operated anytime and anywhere, and are convenient for users to use for processing Business or for entertainment purposes such as listening to music. Nowadays, in order to meet the differen...

[0003] Based on the above, since different types of portable devices use different specifications of power converters, if people have multiple portable devices at home, it is often easy to take the power converter by mistake because they are in a hurry to go out. Because the specifications of the power converter do not meet the specifications of the portable device, for example, the rated power of the power converter is lower than the power required by the portable device, resulting in the situation that the portable device cannot operate normally or even suddenly shuts down during the operation of the user , so prone to data corruption

[0004] Furthermore, when a user is using a portable device, if he executes a software program that consumes too much resources, such as a 3D game, a software program for processing 3D images, a central processing unit (CPU) test program or a display card test program, then It consumes a lot of power of the portable device. If other software programs are executed at the same time, the power converter will not be able to provide sufficient output power to the portable device, which will affect the normal operation of the portable device and even cause the above-mentioned sudden shutdown. situation
