PD70211

PD Controller with Switching Regulator for

AF/AT/UPOE/HDBaseT/4-pair PoE Applications

f

Description

PD70211 is an advanced PD Interface IC with

integrated switching (PWM) regulator control

for

Powered Devices in PoE applications.

It supports

IEEE802.3af, IEEE802at, HDBaseT and general 2/4-pair

configurations.

The

PD70211

front-end

includes

an

advanced

classification block that supports 2, 3, 4, and 6 event

classification. Using the SUPP_Sx pins, it also identifies

which of the four pairs of the cable actually receives

power and generates appropriate flags.

The IC features an internal bleeder for discharging the

input capacitor of the DC/DC converter rapidly, so as

to ensure fast re-detection and port power-up in case

of sudden removal and re-insertion of the Ethernet

cable into the RJ-45. The advanced PWM current-

mode section supports synchronous Flyback and Active

clamp Forward topologies, as well as Buck, Boost etc.

.

Features

 Supports IEEE802.3af/at, HDBaseT and other 2-

pair/4-pair configurations

 Wall-adapter support (Rear Aux method)

 PD detection & programmable classification

 2,3,4, and 6 event classification

 Integrated 0.3Ω isolating (series-pass) FET

 Inrush current limiting

 Less than 10µA offset current during detection

 Advanced PWM section

 Lead-free MLPQ-36 (6 × 6 mm) package

Applications

 HDBaseT up to 95 Watts

 IEEE802.3af and 802.3at

 Power Forwarding

 Indoor and outdoor PoE
