Title:
CIRCUIT MODULE AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/128987
Kind Code:
A1
Abstract:
Provided in the present application is a circuit module and an electronic device, the circuit module comprising: a power source input end is connected to a first input end of a first switch transistor, and an output end of the first switch transistor is connected to a power source output end; the power source input end is connected to an input end of a booster unit, an output end of the booster unit is connected to the input end of an energy storage unit, an output end of the energy storage unit is connected to an input end of a direct current conversion unit, an output end of the direct current conversion unit is connected to a first input end of a second switch transistor, and an output end of the second switch transistor is connected to the power source output end; the power source input end is connected to a first input end of a comparison unit, a second input end of the comparison unit is used for inputting a preset threshold value, and output ends of the comparison unit are respectively connected to a second input end of the first switch transistor and a second input end of the second switch transistor; when the power source voltage inputted at the power source input end is greater than the preset threshold value, the power source voltage is outputted to the power source output end; or, when the power source voltage is less than or equal to the preset threshold value, a conversion voltage is outputted to the power source output end.
