Introduction
This document focuses on a product evaluation board for a simple, low cost 5 V 2 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.
