Title:
VOLTAGE STABILIZATION MODULE AND ELECTRONIC APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/134452
Kind Code:
A1
Abstract:
Provided are a voltage stabilization module and an electronic apparatus. The voltage stabilization module comprises a voltage output end, a control circuit, a digital voltage stabilization circuit and an analog voltage stabilization circuit, wherein when the voltage stabilization module is started, the control circuit provides a trigger signal to the digital voltage stabilization circuit, and is configured to control, when an output voltage is less than a first voltage or greater than a second voltage, the digital voltage stabilization circuit to operate and the analog voltage stabilization circuit to not operate, and control, when the output voltage is greater than the first voltage and less than the second voltage, the analog voltage stabilization circuit to operate and the digital voltage stabilization circuit to not operate; after receiving the trigger signal, the digital voltage stabilization circuit controls the output voltage to be increased, and when controlled by the control circuit to operate, the digital voltage stabilization circuit controls the output voltage to be adjusted, such that the absolute value of the difference between the output voltage and a reference voltage decreases; and when the analog voltage stabilization circuit is controlled by the control circuit to operate, the output voltage is adjusted to be the reference voltage. By means of the present disclosure, the voltage adjustment speed can be increased, and the voltage adjustment precision can also be guaranteed.
