3 EMxx Evaluation Board User Guide. Description The EMxx are a series of PowerSoC synchronous buck converters from the Intel Enpirion Power Solutions family. The EMxx series feature 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. compliant interface provides setup, control, and telemetry. Differential remote sensing and ±.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..

5 EMxx Evaluation Board User Guide 4. Instructions ) Connect the power supply Set the Power Supply to V/A. Connect the power supply to the board (make sure that the power supply is OFF) with two patch cables, not longer than inches ( 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 eyeletterminated 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 V may cause permanent board damage! ) Connect the load Connect the load to the OUTPUT GROUND and OUTPUT voltage with patch cables, no longer than inches ( cm). Please observe the correct polarity. ) Check jumper settings The board will arrive with one jumper on the J6 (BUS enabling control through PMBUS), one jumper on J4 (INT this enables the on-board 5V power supply) and one jumper on J5 (AUX_PVIN this biases the 5V on board DC-DC converter). If an auxiliary 5V power supply is needed (connected between J6 () and J7 (-)), J4 should be placed across the EXT position while J5 can be removed. Although TRACK and SYNC use 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. 5

6 EMxx 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 : Figure : L and H Jumper Table, Marked On The EMxx Evaluation Board Silk Screen For instruction on how to use the EMxx GUI, please read GUI User Guide. NOTE: To measure the Bode Plot of the DC-DC converter, R must be replaced with 5Ω resistor across which to inject the signal, while TP8, TP, TP8 and TP should be used to connect the probes of the phase analyzer. 6
