| description | The invention relates to the technical field of Ethernet power supply, in particular to a power supply module, power receiving end equipment and an Ethernet power supply system. The power supply module of the Ethernet power receiving end equipment comprises a control chip, a sampling circuit and a first switching circuit, the sampling circuit is connected in series between a power supply input end and a voltage detection end of the control chip, and parameters of the sampling circuit can be adjusted according to specific application. The current in the sampling circuit flows to the post-stage circuit through the first switching circuit, the current of the sampling circuit and the current of the control chip are superposed to jointly form a power supply signal to supply power to the power receiving end equipment, and the output power of the control chip is greatly improved by increasing the current, so that the power supply end equipment with higher power can be met.
