Document Type and Number:
WIPO Patent Application WO/2019/104808
Kind Code:
A1
Abstract:
The present application relates to the technical field of power supply design, and in particular, to a power supply circuit and an adapter. The power supply circuit comprises: a main circuit module; a current mirror module, an input end of the current mirror module being connected to an output end of the main circuit module, and being used for sampling the output current of the main circuit module; and a control module, said control module being connected to an output end of the current mirror module, and being used for adjusting, according to the sampled output current, the output power of the main circuit module. When the current mirror module is in operation, it does not need the power supplied from an external power supply and it can adapt to high and low voltage sampling. Therefore, the power supply circuit has characteristics of low power consumption and wide voltage sampling range.
