Application note
Power over Ethernet - PD converter with 12 V 1 A output,
standard IEEE 802.3af compliant
By Antonio Rotta
Introduction
This document focuses on a reference design for a simple, low cost 12 V 1 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.
