Enpirion EP5358xUI DC/DC Converter
Module Evaluation Board
Introduction
Thank you for choosing Altera Enpirion power products!
This application note describes how to test the EP5358xUI (EP5358LUI,
EP5358HUI) converters using Altera’s Enpirion 2.5mmx2.25mm Module EVAL
BOARD shown in Fig. 1. In addition to this document you will also need the
device datasheet for a thorough evaluation of the power converter module.
The EP5358xUI converters are part of a new class of DC/DC converter products,
a complete power system on chip (PowerSoC):
•
These devices are complete modules including magnetics, and require
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 0603
input capacitor and an 0805 output capacitor.
•
Pads are available to add up to one additional input capacitor and up to
one additional output capacitor for evaluation of performance over a wide
range of input/output capacitor combinations.
•
Pads are available to populate an external resistor divider to enable output
voltage programming of values not available using the VID. The pads are
labeled R1 and R2. Pads are also available for placing an optional feed-
forward capacitor (labeled C9) across resistor R1.
NOTE: The External
voltage divider option is available only with EP5358LUI.
•
Jumpers are provided for easy programming of the following signals:
o
Enable
o
VS0-VS2 output voltage selection pins
•
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 safeguard the device from common setup mishaps.
