General Description

The AS18x4 product family integrates Akros GreenEdge™ Isolation technology with next generation Power-over-Ethernet (PoE) PD and power conversion technology to deliver groundbreaking power integration, and enable a new range of Digital Power PoE PD capabilities and solutions.

A Type 1 (IEEE® 802.3af) and Type 2 (IEEE® 802.3at) pliant PD is integrated with high-voltage isolation and quad-output digital power DC-DC converters – resulting in a plete PoE & Power management solution in a single device with minimal external ponents.

In addition to enabling digital PoE power conversion, Akros GreenEdge™ isolation enables direct digital management of both isolated Primary power and Secondary system power for real time end-to-end Green Power application capabilities.
