Abstract

This application includes a power supply circuit, a PCB circuit board, a power supply device. The power supply circuit includes a processing circuit, a load circuit and a feedback circuit which are sequentially connected. The feedback circuit is connected to an output terminal of the load circuit and an input terminal of the processing circuit, and is configured to obtain a voltage of the output terminal of the load circuit and generate a sampling value. The processing circuit is configured to control a voltage of the output terminal of the load circuit according to the sampling value. The power supply circuit includes a differential circuit which connects the load circuit and the feedback circuit by using a differential trace manner. By means of differential trace manner, accuracy of an obtained sampling value is improved and a stability of a voltage of the output terminal of the load circuit is ensured.
