TPS23754 Power over Ethernet PoE Controller

The TPS23754 Achieves 90% Power Conversion Efficiency - Now Available at Digi-Key

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
