Power supply, control method and electronic device

Abstract

The application discloses a power supply, a control method and an electronic device. The power supply comprises an output module configured to provide an output voltage based on a plurality of input voltages, the plurality of input voltages having different temperature curves; and a temperature selection module configured to provide a temperature indication signal according to an ambient temperature to control the output module, the temperature indication signal being in a first state when the ambient temperature is less than a predetermined temperature, and the temperature indication signal being in a second state when the ambient temperature is greater than or equal to the predetermined temperature, so that an output voltage curve representing a change of the output voltage with temperature is continuous in at least two temperature intervals and has different temperature coefficients. The power supply can flexibly control the output voltage curve of the output voltage, and is well applicable to different devices under different temperatures.
