Application Notes
- High Power PoE PD Using the TPS2375/77-1PDF, 781 Kb, File published: Feb 28, 2006
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.
