STEVAL-TSP005V2：Power over Ethernet - PD converter with 5 V 2 A output, standard IEEE 802.3af compliant
This document focuses on a reference design 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.
