Implementing a 60-W End-to-End PoE System
PDF, 520 Kb, Datei veröffentlicht: Feb 8, 2012
Specialized applications such as WiMax base stations may require more than 50 W of power, but the current IEEE 802.3at standard defines 25.5-W, two-pair systems. This application report presents a nonstandard Power over Ethernet (PoE) system that can deliver 60 W of processed power to the load. The Powered Device (PD) interface is based on a single TPS2379 and an external hotswap MOSFET,permitti
