EVB-EP5358HUI: 1.8 ~ 3.3V @ 600mA, 2.4 ~ 5.5V in, Buck

Summary

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: enable, 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.
