Application note
Power over Ethernet-PD converter with 3.3 V, 3 A output,
standard IEEE 802.3af compliant

Introduction
This document focuses on a demonstration board design for a simple, low cost 3.3 V, 3 A
flyback converter based on the PM8800A device.
The PM8800A is a highly integrated device embedding an IEEE 802.3af compliant
“Powered Device” (PD) interface together with a PWM controller.
It can be successfully used in all low power, low cost PoE applications.
