| Abstract: | Ethernet is the most universal LAN protocol and the Power over Ethern et is a basic device.The circuit design of 15W DC/DC powe r converter module is introduced, which is based on Ethernet interface. The pow er module comp oses of Ethernet interface circuit and high efficiency DC/DC power converter. A lso the module includes PoE identifying signal impedance and "0 type" type circu it. When using a MOSFET switch, the efficiency of PoE interface can arrive at o ver 97%. |
