Title:
DCDC CIRCUIT, POWER ADAPTER, AND VOLTAGE CONVERSION METHOD
Document Type and Number:
WIPO Patent Application WO/2023/185154
Kind Code:
A1
Abstract:
The present application relates to a DCDC circuit, a power adapter, and a voltage conversion method. The DCDC circuit comprises a feedback circuit and a conversion circuit. The feedback circuit is connected to the conversion circuit. The feedback circuit is used for receiving an input voltage inputted by a previous-stage circuit and outputting a reference voltage according to the input voltage; and the conversion circuit is used for performing voltage conversion processing according to the reference voltage to obtain an output voltage. According to embodiments of the present application, the application flexibility of the DCDC circuit can be improved.
