Abstract

The invention relates to a DCDC converter control method and device, a storage medium and electronic equipment, and relates to the technical field of electronic control. The method is applied to a terminal, and the terminal comprises a power amplifier, a power supply and a DCDC converter; the power amplifier is connected with the output end of the DCDC converter, and the power supply is connectedwith the input end of the DCDC converter. The method comprises the following steps: acquiring the transmitting power of the terminal and a power supply voltage of the power supply; obtaining a secondcorresponding relation according to the transmitting power and a preset first corresponding relation, determining a target voltage required by the power amplifier, determining a target load accordingto the power supply voltage, the target voltage and a preset second corresponding relation, and configuring the DCDC converter according to a target load, so that the DCDC converter converts the powersupply voltage into the target voltage to supply power to the power amplifier. The target voltage is determined according to the transmitting power, and then the load configuration of the DCDC converter is determined according to the target voltage and the power supply voltage, so the conversion efficiency of the DCDC converter can be improved on the premise of meeting the transmitting power.

Description

technical field [0001] The present disclosure relates to the technical field of electronic control, and in particular, to a control method, device, storage medium and electronic equipment of a DCDC converter. Background technique [0002] With the continuous development of mobile communication technology, the Internet of Everything, which connects people and things, and things and things, has begun to integrate into people's lives, especially in recent years NB-IoT (English: Narrow Band-Internet of Things, Chinese: Narrowband Internet of Things), EMTC (English: Enhanced Machine-Type Communication, Chinese: Enhanced Internet of Things), MMTC (English: Massive Machine-Type Communications, Chinese: Large-scale Internet of Things) and other technologies continue to develop, making the Internet of Things begin to gain Wide range of applications. The Internet of Things has high requirements on the battery life of the terminal, and it is necessary to reduce the power consumption o...
