Description

technical field [0001] The invention belongs to the technical field of circuits, and more particularly, particularly relates to a charging line circuit without voltage loss. Background technique [0002] Some small electronic devices require relatively lightweight electronic connecting wires, which results in less current passing through the same voltage, so the power supply speed is insufficient. When multiple sets of devices are required to supply power at the same time, the power supply performance will be affected due to differences in lines and devices. . Therefore, in view of this, the existing structure and defects are studied and improved, and a charging line circuit without voltage loss is provided. SUMMARY OF THE INVENTION [0003] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a charging line circuit without voltage loss, which effectively solves the problem that the power supply performance of ...
