Implementation of High Power Power-Over-Ethernet System Based on LTPoE++

Abstract:

A new Power over Ethernet (PoE) proprietary specification known as LTPoE++ and its solution for high power PoE system is introduced. A 90W single port high power PoE system based on the LTPoE++ solution using power sourcing equipment (PSE) controller LTC4274A-4 and powered device (PD) controller LT4275A produced by Linear Technology is illustrated, including overall structure, features, hardware frames, functions and their implementation. Finally working process of the system is analyzed.
