STEVAL-TSP005V2
Power over Ethernet - PD converter with 5 V 2 A output,
standard IEEE 802.3af compliant
Data brief
Description
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 âPowered
Deviceâ (PD) interface together with a PWM
controller.
It can be successfully used in all low power, low
cost PoE applications.
