Use MPS's MP8007H as the main control. The main circuit refers to the official EV8007H-V-00A evaluation board (8007H evaluation board). Remove the DC power supply part. The maximum output power is 11W.
Since the transformer and rectifier bridge cannot be found on the official evaluation board, the TSA-021 transformer of Xunkang Electronics is used, and the ABS210 is used as the rectifier bridge.
The RJ45 signal part has been routed with equal length and a line width of 0.2mm. The routing has not been impedance matched (there should be no problem?)
It is recommended to use the HY601742 POE dedicated transformer for the network port transformer (H1102 should also be fine).
Please see the attached chip datasheet and EV8007H-V-00A manual. This is
 
the first time I design a POE splitter. If there is any deficiency, please correct me!
