Problems solved by technology

However, the operating voltage required by the system is usually about 3.3V, and sometimes the voltage supplied by the battery is sufficient for its operation. Therefore, the traditional power management method will consume power in unnecessary conversion, reducing the power conversion efficiency, and further Shorten the life of the product

Abstract

The invention provides a power supply management system, a power supply management method and an electronic device. The power supply management method comprises the following steps: judging whether supply voltage is smaller than a first voltage value or not; if the supply voltage is smaller than the first voltage value, increasing the supply voltage to the first voltage value so as to operate at least one load; and if the supply voltage is greater than or equal to the first voltage value, directly supplying the supply voltage to the load to operate the load, thus improving the conversion efficiency of the system.

Description

technical field [0001] The invention relates to a power management system and method thereof, in particular to a power management system device and method thereof capable of improving system conversion efficiency. Background technique [0002] With the rapid development of science and technology, digital camera (Digital Still Camera, DSC) products have been continuously introduced in recent years, and consumers' requirements for digital camera functions have also been continuously improved, such as large screen size, GPS satellite navigation, WI-FI function, large-capacity memory , Optical anti-shake, increase the number of photos taken, etc. When there are more product functional requirements, in addition to making the design more complicated, the power supply required will also be more groups, but most of the current digital cameras use lithium batteries (LithiumBattery, Li) and alkaline batteries (AlkalineBattery, AA ) to provide camera power, and the battery voltage wil...
