MAX5992A Evaluation Kit
General Description
Features
The MAX5992A/B evaluation kit (EV kit) is a fully assembled and tested surface-mount circuit board featuring
the MAX5992A/B IEEE® 802.3af/at-compliant network
powered device (PD) interface controller IC, which pro
vides PD detection signature, PD classification signature,
inrush current control, undervoltage lockout (UVLO),
and active FET-bridge driver. The EV kit is a compact
and low-cost design used in power-over-Ethernet (PoE)
applications requiring DC power from an Ethernet
network port for PDs, such as fiber-to-the-femotocell/
picocell/microcell, fiber-to-the-home/fiber-to-the-building
(FTTH/FTTB), IP phones, wireless access nodes, and
security cameras.
●● IEEE 802.3af/at-Compliant PD Interface Circuit
The EV kit features a 2x2P PD or multi-PD redundancy
configuration using the ICs. The 2x2P powers a galvanically isolated 100W, 250kHz switching-frequency, activeclamped, synchronous-rectified forward DC-DC converter
using the MAX5974D. The device circuit achieves high
efficiency by using a forward DC-DC converter topology.
The surface-mount transformer provides up to +1500V
galvanic isolation for the output. The EV kit output voltage
is configured for +12V and provides up to 8.4A load current.

Ordering Information appears at end of data sheet.
Note: In the multi-PD redundancy mode, the total output
power must be reduced to 50W, which is limited by the
LAN transformer on board. Its port current must be limited
to 1.2A per 2 pair.
The EV kit circuit receives its power from IEEE 802.3af/
at-compliant power-sourcing equipment (PSE). The PSE
provides the required -44V to -57V DC power over a
twisted-pair Ethernet network cable to the EV kit’s RJ45
connectors. The EV kit features an active FET bridge for
separating the DC power provided by an end-span or
mid-span Ethernet system.
Warning: The EV kit is designed to operate with high voltages. Dangerous voltages are present on this EV kit and on equipment
connected to it. Users who power up this EV kit, or power the sources connected to it, must be careful to follow safety procedures
appropriately to work with high-voltage electrical equipment.
Under severe fault or failure conditions, this EV kit may dissipate large amounts of power, which could result in the mechanical
ejection of a component or of component debris at high velocity. Operate this kit with care to avoid possible personal injury.

Quick Start
Required Equipment
●● MAX5992A/B EV kit
●● MAX5980 EV kit
●● IEEE 802.3af/at-compliant PSE and Category 5e
Ethernet network cable
●● Two -54V, 15A-capable DC power supply
●● Voltmeter
Procedure
The EV kit is fully assembled and tested. Follow the steps
below to verify board operation. Caution: Do not turn on
the power supply until all connections are completed.
1) Use one of the following methods to power the EV kit:
a) If network connectivity is required: Connect a
Category 5e ethernet network cable from the EV
kit input port’s RJ45 connectors (J1_POWER,
J2_POWER) to the corresponding PSE ethernet
LAN connections, which provide power to the
EV kit. Two modular RJ45 jacks (J1_DATA,
J2_DATA) provide an interface with the ethernet
data signals only.
b) If network connectivity is not required:
Connect a -54V DC power supply between the
-54V1, -V54V2, and GND PCB pads on the EV
kit. Connect the power-supply positive terminal
to the V+ PCB pad and the negative terminal to
the V- PCB pad.
2) Activate the PSE power supply or turn on the external
DC power supply.
3) Using a voltmeter, verify that the EV kit provides
+12V across the VOUT and RTN PCB pads.
Detailed Description of Hardware
(or Software)
The MAX5992A/B EV kit is a fully assembled and tested
surface-mount circuit board that evaluates the MAX5992A/B
IEEE 802.3af/at-compliant network PD interface controller.
The EV kit features two powered Ethernet ports, two dataonly Ethernet ports, and a MAX5974D active-clamped,
current-mode PWM controller IC.
www.maximintegrated.com
Evaluates: MAX5992A
MAX5992B
The EV kit is a 2x2P PD configuration PoE using the
PD controller IC. The 2x2P PD interface powers a
galvanically isolated 100W DC-DC converter using the
MAX5974D active-clamped, current-mode PWM controller
IC in a forward-feedback topology. The EV kit receives
power from two IEEE 802.3af/at-compliant PSEs and two
UTP cables connected to the EV kit’s RJ45 connectors.
The EV kit accepts power from an endspan or midspan
PSE network con figuration. The EV kit also provides
Ethernet jacks J1_DATA and J2_DATA for interfacing to
the Ethernet data signals. PCB pads -54V1, -54V2, and
GND are available for powering the EV kit, if network
connectivity is not required.
The EV kit output voltage is configured for +12V and
provides up to 8.4A output current. The EV kit circuit use
MOSFETs N1 and N2 for synchronous rectification on the
secondary side. Transformer T1 provides up to 1500V
galvanic isolation for the output. Isolated feedback voltage
is achieved using optocoupler U4 and voltage reference
U5. Current-sense resistors R45 and R46 limit the peak
current through transistor N7 and primary transformer T1.
Capacitor C14 and transistor N12 form a clamping
net-work that protects transformer T1 against saturation
due to reverse current, by monitoring the voltage across
the MAX5974D’s CS input during auxiliary driver N4 off-time.
The EV kit accommodates mainly two applications to
exercise: 2x2P and multi-PD redundancy. As a default,
the EV kit is set to 2x2P. Besides these two configurations,
single PD operation can be configured, but power is
limited by the current capability of the LAN transformer,
which supports up to 1.2A per 2P.
In the 2x2P application, there are sets of PoE power lines.
Each PSE has its own PD. The PSEs are all connected to
the same power supply. The two PoE sets share the same
Ethernet cable. Figure 1 is the system-level diagram. To
test the EV kit in 2x2P, the MAX5980A EV kit needs to
reconfigured into 2x2P mode accordingly. Refer to the
MAX5980 EV kit data sheet for more details.
In multi-PD redundancy mode, the PSEs are independent.
The input voltages of each PSE can be different. Each
PSE is connected to its PD through an independent
ethernet cable (see Figure 1).

2x2P PD Configuration
Jumper JU1 sets the 2x2P PD configuration of the devices. See Table 1 for shunt positions.
Power Good (PG)
Jumper JU2 sets the PG output for 2x2P PD and multi-PD
configurations. See Table 2 for shunt positions.
Multi-PD Redundancy Configuration
The EV kit provides an option to configure for multi-PD
redundancy operation. Set jumpers JU1, JU2 accordingly and remove resistors R116, R117 for redundancy
configuration.
Jumper JU3 sets the multi-PD redundancy configuration
of U1. See Table 3 for shunt positions.
Jumper JU4 sets the multi-PD redundancy configuration
of U2. See Table 4 for shunt positions.
PD Classification Signature
The EV kit is configured for a Class 5 (> 25.5W) PD
classification by resistors R51 and R56. To reconfig-ure
the PD classification, replace the surface-mount 0805
resistors, R51 and R56. Table 5 lists the PD classification
options.
