TPS23754PWPR

Product Summary

The TPS23754PWPR is a combined Power over Ethernet (PoE) powered device (PD) interface and current-mode dc/dc controller optimized specifically for isolated converters. The PoE interface supports the IEEE 802.3at (draft) standard. The TPS23754PWPR supports a number of input voltage 2 ORing options including highest voltage, external adapter preference, and PoE preference. These features allow the designer to determine which power source will carry the load under all conditions. The applications of the TPS23754PWPR include IEEE 802.3at (Draft) Compliant Devices, Video and VoIP Telephones, RFID Readers, Multiband Access Points, Security Cameras.
