This user guide supports the evaluation kit for GreenBridge™ and shielded gate
PowerTrench®MOSFET applying to a Power Device (PD) of Power over Ethernet
(PoE). It should be used in conjunction with their datasheets as well as Fairchild’s
application notes and technical support team. Please visit Fairchild’s website at
www.fairchildsemi.com.
1. Introduction
This document describes the proposed solution for PoE++ PD that increases the
delivering power up to 90 W. It is designed to rectify a polarity of DC voltage from
Power Source Equipment (PSE) and then active clamp forward DC-DC converter steps
down a nominal input voltage 48 VIN to output voltage 3.3 VOUT in 300 kHz of the
switching frequency. To deliver 90 W power through a network cable, the power system
is composed with four-pair architecture, which PSE uses to deliver data and power to the
PD through both the spare pair and data pair in the network cable at the same time.
1.1. Description
GreenBridge™ FDMQ8203 replaces the conventional diode bridge to reduce the power
dissipation caused by the large voltage drop of a diode bridge, resulting in a lower power
class power device. The small package size of MLP4.5x5 reduces PCB area and increases
power density. FDMC86102 100 V shielded gate PowerTrench® MOSFET for the hot
swap switch has the low conduction loss and the ruggedness due to the low RDS(on) and
wide safe operating area (SOA). The FDMS86200 150 V shielded gate PowerTrench
MOSFET reduces switching loss and conduction loss in the primary switch of the active
clamp forward topology because it has low FOM (RDS(on) x Qg). The FDMS8025S 30 V
shielded gate PowerTrench MOSFET is optimized for synchronous rectification because
it has the low RDS(on) and outstanding body diode performance.

4.1. Hardware Connector Description
The evaluation kit is fully assembled and tested. Follow the steps below to verify board
operation.
1. Use one of the following methods to power the evaluation kit:
If network connectivity is required:
Connect a network cable from the evaluation kit input port RJ45 connector to the
corresponding PSE Ethernet LAN connection, which provides power to the
evaluation kit such as PoE++ or four-fair architecture.
If network connectivity is not required:
Connect a -48 V DC power supply between the TXCT and RXCT; and
Connect a -48 V DC power supply between the MID+ and MID- together.
Caution: Do not turn on the power supply until all connections are completed.
2. Activate the PSE power supply or turn on the external DC power supply.
3. Using a voltmeter, verify that the evaluation kit provides +3.3 V across the
+VOUT and –VOUT pins. –VOUT is isolated from the evaluation kit’s input
VIN- and AUX- pins.

FAIRCHILD’S PRODUCTS ARE NOT AUTHORIZED FOR USE AS CRITICAL COMPONENTS IN LIFE SUPPORT DEVICES OR SYSTEMS
WITHOUT THE EXPRESS WRITTEN APPROVAL OF THE PRESIDENT OF FAIRCHILD SEMICONDUCTOR CORPORATION.
As used herein:
1. Life support devices or systems are devices or systems which, (a)
are intended for surgical implant into the body, or (b) support or
sustain life, or (c) whose failure to perform when properly used in
accordance with instructions for use provided in the labeling, can be
reasonably expected to result in significant injury to the user.

ANTI-COUNTERFEITING POLICY
Fairchild Semiconductor Corporation's Anti-Counterfeiting Policy. Fairchild's Anti-Counterfeiting Policy is also stated on our external website,
www.fairchildsemi.com, under Sales Support.
Counterfeiting of semiconductor parts is a growing problem in the industry. All manufacturers of semiconductor products are experiencing
counterfeiting of their parts. Customers who inadvertently purchase counterfeit parts experience many problems such as loss of brand reputation,
substandard performance, failed applications, and increased cost of production and manufacturing delays. Fairchild is taking strong measures to
protect ourselves and our customers from the proliferation of counterfeit parts. Fairchild strongly encourages customers to purchase Fairchild parts
either directly from Fairchild or from Authorized Fairchild Distributors who are listed by country on our web page cited above. Products customers buy
either from Fairchild directly or from Authorized Fairchild Distributors are genuine parts, have full traceability, meet Fairchild's quality standards for
handling and storage and provide access to Fairchild's full range of up-to-date technical and product information. Fairchild and our Authorized
Distributors will stand behind all warranties and will appropriately address any warranty issues that may arise. Fairchild will not provide any warranty
coverage or other assistance for parts bought from Unauthorized Sources. Fairchild is committed to combat this global problem and encourage our
customers to do their part in stopping this practice by buying direct or from authorized distributors.
