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:
o Enable
o VOUT 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 Start Guide
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 (-).
