This document details the characteristics and performances of the PM8800 demonstration kit which has been designed to cover a broad range of power over Ethernet (PoE) applications. PM8800 is a highly integrated device embedding an IEEE802.3af compliant powered device (PD) interface together with a PWM controller and support for auxiliary sources.View Design
Demonstration circuit 1145B, featuring the LTC®4267, provides a complete IEEE 802.3af Powered Device (PD) interface and isolated 12V at 0.9A power supply solution for use in Power over Ethernet (PoE) applications. An optional connection is included for a 12V auxiliary supply on the secondary side that disables PoE when present.View Design
The NCP1081SPCGEVB implements a PoE power splitter that converts the voltage on the Ethernet cable to a lower voltage. The board is equipped with 2 RJ45 connectors, one connector serves as the data and power input and the other connector is the data output. Ethernet data is untouched by the board and simply forwarded.
Close to the switching MOSFET voltages on the board may exceed 20…
