Title:
VOLTAGE REGULATOR AND CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/173595
Kind Code:
A1
Abstract:
A voltage regulator and a control method therefor. The voltage regulator comprises: a comparison module (100), which is configured to compare a reference voltage (10a) with a feedback voltage (10b), and generate an error voltage (10c) on the basis of the comparison; an output voltage regulation module (101), which is coupled to an output end of the comparison module (100) at a first node (102), and is configured to adjust, on the basis of the error voltage (10c), an input voltage received by the output voltage regulation module (101), so as to provide an output voltage (10d) to an output node (103); a feedback circuit (104), which is coupled between the output node (103) and a grounding voltage, wherein the feedback circuit (104) is configured to perform voltage division on the output voltage (10d), so as to provide the feedback voltage (10b); and a driving voltage regulation module (105), which is coupled to the first node (102) and is used for regulating the potential at the first node (102) during a start-up stage of the operation of the voltage regulator. The voltage regulator and the control method are beneficial to accelerating the start-up of the voltage regulator.
