EM22xx Evaluation Board User Guide
1. Description
The EM22xx family are PowerSoC synchronous Dual Phase buck converters from the Intel® Enpirion® Power Solutions family. The EM22xx series feature an advanced controller, gate drivers, synchronous MOSFET switches, and high performance inductors. Only input and output filter capacitors and a few small signal components are required for a complete solution.
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.

EM22xx Evaluation Board User Guide
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 6 inches (15 cm). Using longer wires is possible, provided that additional bulk is added to the board and the input voltage is monitored at the board level. For lower Input voltages e.g. 5V further bulk capacitance maybe required depending on the Power Supply being used. Please use INPUT GROUND and INPUT VOLTAGE eyelet-terminated cables to connect the power.
Please observe the correct polarity.
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 6 inches (15 cm).
Please observe the correct polarity.
3) Check jumper settings
The board will arrive with one jumper on the J6 (enabling the Output through pulling
the CTRL pin high), one jumper on J14 (INT – this connects the on-board 5VCC supply) and one jumper on J15 (PVIN_5V – 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. If operating PVIN at 6V or lower an external 5V supply is required to ensure correct operation. (For PVIN values below 6V the on-board switcher cannot guarantee a 5Vout output)
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.

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; 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. The voltage range is marked on the board, as shown in Figure 2:

Figure 2: Jumper Table, Marked On The EM22xx Evaluation Board Silk Screen
For instruction on how to use the EM22xx GUI, please read “GUI User Guide.”
NOTE: To measure the Bode Plot of the DC-DC converter, J12 must be populated which is then used to connect the
probes of the phase analyzer.
