Problems solved by technology

However, when the handheld device is in the standby state, the output current of the DC / DC converter is often small, and its corresponding working efficiency will rapidly decay at this time
In this way, the power supply mode of the handheld device in the prior art will cause the standby efficiency of the handheld device to be quite low, thereby affecting the standby time of the handheld device

Abstract

An embodiment of the invention provides an apparatus of increasing hand-held equipment standby efficiency and a method thereof. The apparatus comprises a power supply, a phase inverter, a field-effect tube, a DC / DC converter and a low drop-out voltage stabilizer, wherein the DC / DC converter and the low drop-out voltage stabilizer are connected in parallel. The power supply provides input voltages for the DC / DC converter and the low drop-out voltage stabilizer. An input port of the phase inverter is connected to an enabled port of the low drop-out voltage stabilizer. The input port of the phase inverter is connected to an enabled port of the DC / DC converter. A grid electrode of the field-effect tube is connected to an output port of the phase inverter. A drain electrode is connected to an output port of the DC / DC converter. A source electrode is connected to an output port of the low drop-out voltage stabilizer. By using the apparatus of increasing the hand-held equipment standby efficiency and the method thereof provided in the embodiment, efficiency of hand-held equipment in a standby state can be increased.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of mobile terminal equipment, and in particular, to an apparatus and method for improving standby efficiency of a handheld equipment. Background technique [0002] In recent years, with the continuous development of mobile terminals, mobile terminals have become quite popular in people's daily life, and many handheld devices that are getting smaller and smaller and have complete functions are also loved by more and more people. Handheld devices The wide application of the technology has shortened the distance between people in time and space, so that people have higher and higher requirements for future handheld devices. Will future communication products provide more convenient and efficient functions and services to become Communication product manufacturers need to pay attention to and research issues. [0003] Taking mobile phones as an example, as we all know, the mobile phone har...
