Evaluating the ADM1272 High Voltage Positive Hot Swap Controller andDigital Power Monitor with PMBusFEATURES

GENERAL DESCRIPTION

Fully functional support evaluation kit for the ADM1272
Populated and tested with 48 V, 30 A, 1 mF design
40 V undervoltage and 60 V overvoltage settings
Custom N-MOSFET footprint suits different packages
Supports up to 2 sense resistors in parallel
Supports up to 4 FETs in parallel
LED indicated status outputs
Wide input voltage range: 16 V to 80 V
120 V absolute maximum
FET temperature measurement capability
Supports cascade setup for multiple boards
Toggle and push-button switch for easy input control
PMBus (I2C) communication supported

The EVAL-ADM1272EBZ is a compact, full featured evaluation
board for the ADM1272. 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 todissipate heat for some of the key components on the power
path, allowing the evaluation of high current hot swap setups.
Two sense resistor slots and four (two on the bottom side)
multipackage FET slots provide great flexibility and allow awide range of application setups.
Multiple test points allow easy access to all critical points andpins. Six LEDs provide direct visual indication on variations in
the board status, such as supply input, output, GPIO1, GPIO2,
power good, and fault.

PACKAGE CONTENTS
EVAL-ADM1272EBZ evaluation board

ADDITIONAL HARDWARE NEEDED
Serial input/output interface, USB-SDP-CABLEZ (not includedin the evaluation kit, must be ordered separately)
Only one dongle is required in multiple board cascade setup

SOFTWARE NEEDED
Analog Devices, Inc., hot swap and power monitoring
evaluation software (download from ADM1272 productpage)

The kit supports PMBus™ communication, allowing the user
to communicate with the ADM1272. The evaluation kit also
supports cascade setup so that multiple evaluation boards canbe connected together and share the same PMBus.
The boards are fully compatible with the ADM1272 evaluation
software, which can be downloaded from the ADM1272
product page.
A USB-to-I2C dongle (USB-SDP-CABLEZ) is required to use
the evaluation software.
The standard evaluation kit is prepopulated and tested with a
48 V, 30 A hot swap design capable of working with a 1 mF
output capacitor.
Complete specifications for the ADM1272 are available in the
ADM1272 data sheet, which must be consulted in conjunction
with this user guide when using the evaluation board.

PLEASE SEE THE LAST PAGE FOR AN IMPORTANT
WARNING AND LEGAL TERMS AND CONDITIONS.

QUICK START GUIDE6.

To set up and start using the evaluation board, take thefollowing steps:
1.

2.

3.
4.

5.

Download the hot swap and power monitoring softwarefrom the ADM1272 product page (see the UG-353 formore information).
Connect the evaluation board (EVAL-ADM1272EBZ) to a
PC through the 10-way connector and the USB-to-I2C
dongle (USB-SDP-CABLEZ).
Connect the power supply to the evaluation board 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 48 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 evaluation board illuminates.
Push the ENABLE switch to the off position or press thepush button on the evaluation board. The green LED(labeled PWRGD) turns off and then turns back on again
when reenabled.

The restart signal can be provided using the RST switch(S3). Pressing this switch disables the output, and it isautomatically reenabled after the restart time has elapsed(default is approximately 10 sec).
7. If a fault event occurs (for example, a short circuit during
operation), the red LED (labeled FAULT) illuminates. Thisfault can be cleared by toggling the ENABLE pin after thefault condition has been removed.
8. Disable the hot swap using the Hot Swap Control sectionin the Basic Operation tab of the software graphical userinterface (GUI). Disabling the hot swap turns off the green
LED (labeled PWRGD) on the evaluation board.
9. Manually program the sense resistor value, if required,using the options in the GUI.
10. Check that the voltage and current measurements are as
expected (for example, VIN = 48 V) in the Power Monitor
tab of the software GUI.

UG-990EVALUATION BOARD DESCRIPTION
The EVAL-ADM1272EBZ evaluation board is designed todemonstrate several features of the ADM1272. A simplified
diagram of the evaluation board is shown in Figure 2.

CONFIGURATIONThe evaluation board is connected to a PC using a USB-to-I2C
dongle (USB-SDP-CABLEZ) for PMBus communication. The
evaluation board is shown in Figure 1.

14541-002

To minimize inductance and losses, use appropriately rated
wires between the power supply, the evaluation board
connectors, and the load. There is only one GND connector, so
the main system current does not normally flow through theevaluation board.

The EVAL-ADM1272EBZ evaluation board is configured tooperate between 40 V and 60 V, with a current limit of 30 A.
Loads with up to 1000 μF of capacitance can be connected. This
capacitance is not included on the board, because it is intended
to be plugged into a system where load capacitance alreadyexists. If load capacitance does not already exist, add
capacitance across the load using the J2 (VOUT) and J3 (GND)
connectors, or solder across D6 and/or on the bottom side pads
under D6. To prevent faults at power up, take care to avoid any
dc loads being enabled until after PWRGD is asserted.

MOSFETSThe EVAL-ADM1272EBZ uses a custom MOSFET footprint,
shown in Figure 3, to accommodate a variety of common
MOSFET packages. Examples include D2PAK, DPAK, LFPAK,
and other SO-8 variants.

Sense resistors must be tested independently. It is the
responsibility of the user to ensure that the layout dimensions
and structure of the footprint comply with individual SMT
manufacturing requirements.

Figure 3. Multipackage N-Channel MOSFET Footprint

SENSE RESISTORSFor optimum current sensing accuracy with standard 2512
sense resistors, the footprint shown in Figure 4 is preferred.
This footprint may not be optimized to all resistors, and results
may vary depending on resistor composition and size.
The center pads are used as the Kelvin connection to sense thevoltage at the resistor. Some resistors provide more accurate
results if sensed at the outer edge of the resistor (labeled A in
Figure 4). Alternatively, the user can configure the senseconnections to be made through center locations (labeled B
in Figure 4), which may yield better results for certain resistor
types. The board can be configured through the eight resistors
located on the underside of the printed circuit board (PCB),
directly under the sense resistors. R7O, R8O, R17O, and R18O
connect the outside vias (labeled A in Figure 4), and R7I, R8I,
R17I, and R18I connect the inside vias (labeled B in Figure 4).
The outside vias are connected by default.
