TPS23754 Power over Ethernet PoE Controller

The TPS23754 is Texas Instruments' latest high-efficiency, high-power Power-over-Ethernet (PoE) controller for 13 watt or 26 watt powered device (PD) applications, such as IP phones, wireless access points, or security cameras. Fully compliant to the IEEE 802.3 at draft 4.0 standard, the integrated TPS23754 supports DC/DC converter topologies that can achieve higher than 90 percent power conversion efficiency, which reduces heat and increases reliability of the system.

Overview

• Supports high-efficiency isolated flyback and forward DC-DC converter topologies
• Implements IEEE 802.3 at (draft 4.0) for PD applications requiring greater than 13 W
• Natively supports external, local power sources with or without PoE power present
• PD front end protects against current inrush and short circuits
• Robust manufacturing process withstands voltage surges up to 100 V at the IC
