EP53x2Q PowerSoC
Enpirion EP53x2QI family of DCDC
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:
• The EP53x2QI is a complete module including magnetics and requiring
only ceramic input and output capacitors.
• The evaluation board is designed to offer a wide range of engineering
evaluation capabilities. This includes the base configuration of an 0805
2.2uF input capacitor for EP5352QI and EP5362QI models and 4.7uF
input capacitor for EP5382QI models, and an 0805 10uF output capacitor.
• Pads are available to add up to one additional input capacitor and up to
two additional output capacitors to allow for evaluation of performance
over a wide range of input/output capacitor combinations.
• Pads are available to populate an external divider if desired.
• Easy jumpers are provided for the following signals:
o Enable
o VS0-VS2 output voltage select
• Numerous test points are provided as well as clip leads for input and
output connections
• The board comes with input decoupling and 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 “ENA” jumper to the Disable Position.
CAUTION: the signal pins, ENA, VS0, VS1, and VS2
must be connected to a “high” or a “low”. If left floating
the state is indeterminate.
STEP 2: Set the output voltage select pins for the desired output voltage setting.
Refer to the section on output voltage select to
determine the setting.
