Some specialized applications require more power than 12.95 W allowed by the IEEE802.3af standard. This application report discusses techniques for implementing nonstandard high-power systems with an emphasis on the powered device (PD). A specific design example of a 27-W, two-pair PD front end is presented along with test results. This type of solution bridges between the existing IEEE 802.3af a - 25-W, High-Power PoE Using the TPS2376-HPDF, 958 Kb, Archivo publicado: oct 13, 2006
This document describes the characteristics, operation, and use of reference design PR567A demonstrating high-power Power-over-Ethernet (PoE). Typical PoE applications consist of two parts: 1) power sourcing equipment (PSE) that injects power into the Ethernet Category 5 (CAT5) cable and 2) powered devices (PD) that connect to the CAT5 cable to receive power.

Two generations of powered device (PD) controllers are available from Texas Instruments for Power-over-Ethernet PD solutions. They are the TPS2370/TPS2371 and the TPS2375/TPS2377. While they are largely pin-compatible, some differences between these two families of PD controllers make the TPS2375 and TPS2377 the preferred devices. This report explains the major differences between the two families - Lightning Surge Considerations for PoE Powered DevicesPDF, 197 Kb, Archivo publicado: abr 30, 2015
