LM5070AE EVAL: POE, 3.3V @ 3.3A Out

Summary

The LM5070 AE (Area Efficient) evaluation board is designed to provide an IEEE802.3af compliant, Power over Ethernet (PoE) power supply.

The power supply features the LM5070 PoE powered device (PD) interface and controller integrated circuit (IC) configured in the versatile flyback topology.

The board features a fully isolated solution, but you have the freedom to transform the circuit into a non-isolated regulator if you desire. Several schematic versions are supplied in this document to those ends.
