Abstract

The invention belongs to the field of power supplies, and provides a power supply circuit and a power supply circuit protective circuit thereof. By adopting the power supply circuit protective circuit, which comprises a sampling module, a reference voltage generation module, a comparison module and a drive control module, in the power supply circuit, the power supply circuit is simple in circuit structural design, low in cost, low in power consumption and high in efficiency, and reduces development difficulty and cost output.

Description

technical field [0001] The invention belongs to the field of power supplies, in particular to a power supply circuit and a protection circuit for the power supply circuit. [0002] Background technique [0003] At present, the power supply circuit has been widely used in learning and living production as a device for supplementing electric energy of electronic equipment. When supplementing electric energy to electronic equipment, if the output terminal of the power supply circuit outputs abnormally due to various accidents, it will damage the internal circuit. [0004] In view of the above-mentioned problems existing when the output of the power supply circuit is abnormal, the internal circuit design of the existing power supply circuit is complicated and the efficiency is low, which increases the difficulty of development and the output of power consumption. [0005] Contents of the invention [0006] The object of the present invention is to provide a protection...
