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,

Fits the on-board LD1 socket

4 channels, 0.5 GHz BW

>30A capability, eyelet terminal, 4 mm

diameter hole, 10 mm outer diameter

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

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.

 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.

 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:

 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
