The embodiment of the invention discloses a voltage adjusting method based on a mobile terminal framework and a mobile terminal. The mobile terminal comprises a central processor and periphery functional modules, wherein the periphery functional modules comprise a power source module, and the central processor is in communication connection with the periphery functional modules. The method comprises the steps that the power source module obtains a first load state of a first functional module, wherein the first functional module is any one of the periphery functional modules; the power source module generates a first voltage control signal which corresponds to the first load state according to a corresponding relation between the load state and a voltage control signal; the power source module controls a first low dropout regulator LDO to output target voltage which corresponds to the first voltage control signal to the first functional module. The voltage adjusting method based on the mobile terminal framework and the mobile terminal are conductive to the reducing of the power dissipation of the mobile terminal.
Description
technical field [0001] The present invention relates to the technical field of mobile terminals, in particular to a voltage adjustment method based on a mobile terminal architecture and a mobile terminal. Background technique [0002] At present, the power supply module (for example, power manager) of the terminal provides power supply voltage for all modules on the terminal, and different modules may require different voltages. In order to ensure that each module can operate normally, the power supply However, when the mobile phone is in the standby state, if the power supply is still supplied with the normal working voltage, the power consumption of these modules will be increased. Contents of the invention [0003] Embodiments of the present invention provide a mobile terminal architecture-based voltage adjustment method and a mobile terminal, which can reduce power consumption of the mobile terminal. [0004] The first aspect of the embodiments of the present inventio...
