STEVAL-TSP006V2 Datasheet, PDF (1/7 Pages) STMicroelectronics – IEEE 802.3af compliant PD interface

STEVAL-TSP006V2
Power over Ethernet - PD converter with 3.3 V 3 A output,
standard IEEE 802.3af compliant
Data brief
Description
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.
Features
 IEEE 802.3af compliant PD interface
 Works with power supplied from Ethernet LAN
cables or from local auxiliary sources
 Line input voltage range: 40 Vdc to 60 Vdc,
output voltage: 3.3 Vdc ± 5%
 Output current: 3 A
 Peak-to-peak output ripple: 30 mV
 Efficiency DC-DC full-load: > 83%
 Efficiency overall peak: > 80%
 Transient response Vout_pk-pk to 50% load
step: < 400 mV_pp
 V in load line case: < 0.5%
