Notas de aplicación
- Implementing a 60-W End-to-End PoE SystemPDF, 520 Kb, Archivo publicado: 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 - Lightning Surge Considerations for PoE Powered DevicesPDF, 197 Kb, Archivo publicado: abr 30, 2015
