EP5348UI PowerSoC
Enpirion EP5348UI 400mA Synchronous
DC/DC Converter Module Evaluation Board
Introduction
Thank you for choosing Altera Enpirion power products!
You are evaluating a new class of DCDC converter product, a complete power
system on silicon. This user guide is applicable to evaluation boards part number
05194 Rev A on the PCB back side. In addition to this document, you will also
need the latest device datasheet.
•The EP5348UI is a complete module with integrated magnetics.
•The evaluation board is designed to offer a wide range of engineering
evaluation capabilities.
•Output voltage is programmed using a resistor divider. The board comes
populated with four pre-placed resistors and a jumper to choose one of
four preset output voltages.
•Easy jumpers are provided for the following signals:
oEnable
oVOUT selection
•Numerous test points are provided as well as clip leads for input and
output connections
•The board comes with input decoupling and input reverse polarity
protection to protect the device from common setup mishaps.
Quick StartGuide
Figure 1 shows a top view of the evaluation board.
STEP 1: Set the “ENABLE” jumper J1 to the Disable Position, as
shown here.
STEP 2: Set the output voltage by setting jumper J4 to one of the pre selected
output voltage settings. See the Output Voltage Select section.
STEP 3: Connect Power Supply to the input clip leads, VIN (+) and GND (-).
CAUTION:Even though the evaluation board comes with reverse polarity
protection diodes, be mindful of the polarity.
STEP 4: Connect the load to the output clip leads VOUT (+) and GND (-).
