Power conversion structure and electronic equipment including the same

Abstract

The present invention proposes a power conversion structure and electronic equipment including it, which relates to the field of power supply. By setting a voltage regulation module connected to the switched capacitor converter, the voltage regulation module receives the first voltage of the switched capacitor converter, and can convert the second voltage to the switched capacitor converter. One voltage is converted into a second voltage, and the second voltage is higher than the current voltage of the battery pack, so that during the use of the electronic device, if the voltage output to the load of the electronic device drops below the threshold voltage, it will be output to the electronic device. The voltage of the load of the device is raised to be higher than the voltage of the current battery pack, so as to avoid customer experience such as black screen or even shutdown of the electronic device, and the working together of the switched capacitor converter and the voltage regulation module can reduce the number of switch tubes, making the device The power conversion structure provided by the application has small size and low cost.

Description

technical field [0001] The invention relates to the field of power supply, in particular to a power conversion structure and electronic equipment including the power conversion structure. Background technique [0002] With the continuous advancement of technology, various electronic devices, such as portable devices (including mobile phones, tablet computers, digital cameras, MP3 players and / or other similar electronic devices) have become popular. Each electronic device may employ a plurality of rechargeable battery cells connected in series and / or in parallel to form a rechargeable battery pack for storing electrical energy. Rechargeable battery packs can be recharged by an adapter connected to the electronic device and a power conversion structure within the electronic device to recover the energy of the battery, rechargeable battery packs can be various types of batteries such as lithium-ion (Li-ion) batteries Group. [0003] During the use of electronic equipment, it ...
