Title:
POWER SUPPLY CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2021/128566
Kind Code:
A1
Abstract:
Provided is a power supply circuit, comprising: a voltage division circuit, a first end of the voltage division circuit being an output end, and a second end of the voltage division circuit being grounded; a control circuit, a first end of the control circuit being connected to the output end, a second end of the control circuit being a feedback end and being connected to the voltage division circuit, and a third end of the control circuit being an input end; and a feedback capacitor, a first end of the feedback capacitor being connected to the output end, and a second end of the feedback capacitor being connected to the voltage division circuit. In the power supply circuit, the feedback capacitor is added between the output end and the feedback end, so that the voltage change situation of the output end can be rapidly provided to the feedback end, and the adjustment of an output voltage is accelerated.
