Update: 28 September, 2023
This application note describes the STEVAL-TSP001V1 demonstration board for the evaluation of a power over Ethernet (PoE) system used to transmit electrical power, along with data, to remote devices over a standard twisted-pair cable in an Ethernet network. A complete power solution for Ethernet-connected powered devices is presented. The power supply fully complies with IEEE 802.3-2005 PoE specifications and delivers the rated output from any compliant source. Example outputs of 3.3 V and 12 V are given in this document, but other requirements can easily be met by implementing small changes.
