1. Description
The EM2130 is a 30A PowerSoC synchronous buck converter from the Intel® Enpirion® Power
Solutions family. The EM2130 features an advanced digital controller, gate drivers, synchronous
MOSFET switches, and a high performance inductor. Only input and output filter capacitors and
a few small signal components are required for a complete solution. A PMBus™ version 1.2
compliant interface provides setup, control, and telemetry.
Differential remote sensing and ±0.5% set-point accuracy provide precise regulation over line,
load and temperature variation. Very low ripple further reduces accuracy uncertainty to provide
best in class static regulation for today’s FPGAs, ASICs, processors, and DDR memory devices.

4. Instructions
1) Connect the power supply
Set the Power Supply to 12V/10A.
Connect the power supply to the board (make sure that the power supply is OFF) with
two patch cables, not longer than 12 inches (30 cm). Using longer wires is possible,
provided that additional bulk is added to the board (the C45 through-hole capacitor
footprint is available for this purpose) and the input voltage is monitored at the board
level. Please use INPUT GROUND and INPUT VOLTAGE eyelet-terminated cables to
connect the power.
Please observe the correct polarity.
CAUTION: Incorrect polarity of the power supply may cause permanent
board damage!
CAUTION: Power supply voltage above 20V may cause permanent board
damage!
2) Connect the load
Connect the load to the OUTPUT GROUND and OUTPUT voltage with patch cables, no
longer than 12 inches (30 cm).
Please observe the correct polarity.
3) Check jumper settings
The board will arrive with one jumper on the J6 (BUS – enabling control through PMBUS),
one jumper on J14 (INT – this enables the on-board 5V power supply) and one jumper
on J15 (AUX_PVIN – this biases the 5V on board DC-DC converter). If an auxiliary 5V
power supply is needed (connected between J16 (+) and J17 (-)), J14 should be placed
across the “EXT” position while J15 can be removed.
Although “TRACK” and “SYNC” use 100 mils headers, they are NOT to be shorted by
jumpers.
4) Connect the PMBUS GUI interface dongle
The USB Dongle can be inserted only in the correct position, with pin one towards GND.
All pins must be properly inserted.
Prerequisite: the latest GUI software must be installed on a Windows PC.
User Guide | Intel® Enpirion® Power Solutions
EM2130 Evaluation Board User Guide

5) Set the output voltage
Using the chart from the silkscreen, please select the desired output voltage, using ONLY
ONE switch ON. This setting will be read by the module when the part is powered on or
by PMBus command; changing the resistor on the fly will not have any effect.
6) Power-up the board
After all preparations above, the board should be ready to perform. If the GUI interface
dongle is not used, the jumper J6 should be moved to the “ON” position; else the jumper
J6 should be in the “BUS” position.
The voltage range (High/Low) is marked on the board, as shown in Figure 2:
Figure 2: “L” and “H” Jumper Table, Marked On The EM2130 Evaluation Board Silk Screen
For instruction on how to use the EM2130 GUI, please read “GUI User Guide.”
NOTE: To measure the Bode Plot of the DC-DC converter, R12 must be replaced with 50Ω resistor across which to inject the
signal, while TP18, TP20, TP8 and TP21 should be used to connect the probes of the phase analyzer.
