STEVAL-TSP006V2:Power over Ethernet - PD converter with 3.3 V 3 A output, standard IEEE 802.3af compliant

This document focuses on a reference 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.

Key Features
