Power Over Ethernet (PoE) Solutions for High-Powered Devices and Power Sourcing Equipment
 TI offers a complete portfolio of PoE ICs for Power Sourcing Equipment (PSE) and Powered Devices (PDs). With solutions for a variety of PoE applications such as VoIP telephones, security cameras, thin/zero-client monitors, RFID readers and wireless access points; our controllers enable IEEE 802.3af, IEEE 802.3at and Universal Power over Ethernet (UPOE) compliant solutions. We also offer reference designs, topical application notes and open-source Link-Layer Discovery Protocol (LLDP) software (coming soon!) to make our PoE solutions easy to design-in. Check out our latest PoE family members – the TPS2378 and TPS2379 – aimed at equipment requiring >25.5W of delivered PoE power!
