The EVAL-ADM1278EBZ is a compact, full featured evaluation
board for the ADM1278. The board layout provides a clear visual
of all the peripheral components and the hot swap power path.
The layout also maximizes the ability of the board to dissipate
heat for some of the key components on the power path, allowing
the evaluation of very high current hot swap setups.
Four sense-resistor slots and six multipackage FET slots provide
great flexibility and allow a wide range of application setups.
PACKAGE CONTENTS
EVAL-ADM1278EBZ evaluation board
ADDITIONAL HARDWARE NEEDED
Serial I/O interface USB-SDP-CABLEZ (not included in the
evaluation kit and should be ordered separately)

EVALUATION BOARD CONNECTION DIAGRAM
Multiple test points allow easy access to all critical points/pins.
Seven LEDs provide direct visual indication on variations in
the board status, such as supply input, output, IC power-good
output, fault output, current sense output, and general-purpose
outputs (GPO). An AD7291 8-channel, I2C, 12-bit, successive
approximation analog-to-digital converter (SAR ADC) allows
users to measure voltages such as CSOUT and other pin voltages,
as well as to read ambient board temperature through an I2C bus
in real time.
The kit supports I2C communication, allowing users to
communicate with the ADM1278. The evaluation kit also
supports cascade setup so multiple evaluation boards can be
connected together and share the same I2C bus.
The boards are fully compatible with the ADM1278 evaluation
software tool, which can be downloaded from the ADM1278
product page.
Users need a USB-SDP-CABLEZ USB-to-I2C dongle to use the
evaluation software tools.

QUICK START GUIDE
6.
To set up and start using the evaluation board, take the
following steps:
1.
2.
3.
4.
5.
Download the hot swap and power monitor software from
www.analog.com/hotswaptools (see the UG-353 user guide
for more information).
Connect the evaluation board (EVAL-ADM1278EBZ) to a
PC through the 10-way connector and USB-SDP-CABLEZ.
Connect the power supply to the evaluation board (EVALADM1278EBZ) using thick wires suitable for the current
levels to be observed.
To confirm that the boards are configured correctly, set
the output of the power supply to 12 V with less than 1 A
current limit and with no load capacitance. If the boards
are configured correctly, the green LED, labeled PWRGD
on the EVAL-ADM1278EBZ, should illuminate.
Push the ENABLE switch to the off position or press the
push-button on the EVAL-ADM1278EBZ. The green LED,
labeled PWRGD, should turn off and then turn back on
again when re-enabled.

Rev. A | Page 3 of 18
If a fault event occurs (for example, a short circuit during
operation), the red LED, labeled FAULT, illuminates. This
fault can be cleared by toggling the ENABLE pin after the
fault condition has been removed.
Disable the hot swap using the Hot Swap Control section
of the Basic Operation tab of the GUI. Disabling the hot
swap turns off the green LED (PWRGD) on the evaluation
board.
Manually program the sense resistor value, if required,
using the options in the GUI.
Check that the voltage and current measurements are as
expected (for example, VIN = 12 V) in the Power Monitor
tab of the software GUI.

EVALUATION BOARD DESCRIPTION
The board is intended to be plugged into a system where load
capacitance already exists. Two through-hole vias are provided
to allow the placement of a load capacitor on the board when
testing the board outside of a real system. All testing performed
on the board was done with a 3 mF load capacitor.
The EVAL-ADM1278EBZ is designed to demonstrate several
features of the ADM1278. A simplified drawing of the evaluation
board is shown in Figure 2.
The EVAL-ADM1278EBZ is connected to a PC using a USBSDP-CABLEZ dongle for I2C communication.
The EVAL-ADM1278EBZ uses a 10 nF CTIMER1 capacitor to
maintain a 1 ms FET safe operating area (SOA). The undervoltage
and overvoltage thresholds were set using resistor dividers. A
resistor divider was also used on the ISET pin to set the current
limit to approximately 73 A. The constant power level was set to
180 W to allow the board to power up while maintaining the
FET SOA at all times. These values can all be fine-tuned further
if necessary.
The EVAL-ADM1278EBZ is shown in Figure 1. To minimize
inductance, use thick wires between the power supply and the
EVAL-ADM1278EBZ board connector. The PWRGD, VIN, and
VOUT LEDs illuminate green after the board is powered.

CSOUT
EVAL-ADM1278EBZ User Guide
UG-601
The EVAL-ADM1278EBZ has the capability to mimic power
throttling by allowing the user to set a programmable threshold
on CSOUT. There is a resistor divider on the board to set the
CSOUT within the input threshold range of the ADC, and another
resistor divider is used to set it within the input threshold range
of the comparator. When the CSOUT voltage exceeds the
comparator threshold programmed by the AD5622 digital-toanalog converter (DAC) (via the evaluation software), an alert
signal is asserted. The yellow LED (D2) illuminates to mimic
this alert signal. The fast response time of the CSOUT pin to a
load step (typically 10 μs) makes it suitable for fast alerts to
overcurrent events. For example, it can be used to drive the fast
PROCHOT pin of an Intel® processor for power throttling.

For the best current sensing accuracy with the footprint shown
in Figure 5, chip resistors without a nickel barrier layer (usually
green in color) are recommended. The data in this user guide may
not be applicable to all resistors, and results may vary depending
on resistor composition and size. Alternative resistors should be
tested independently. It is the responsibility of the user to ensure
the layout dimensions and structure of the footprint comply with
individual SMT manufacturing requirements. Analog Devices
does not accept responsibility for any issues that may arise as a
result of using this footprint.
