Altera EP53A8LQI Manuals

Enpirion® Power Evaluation Board User Guide EP53A8xQI PowerSoC Enpirion EP53A8xQI DC/DC Converter Module Evaluation Board Introduction Thank you for choosing Altera Enpirion power products! This application note describes how to test the EP53A8LQI and the EP53A8HQI converters using the Altera Enpirion EP53A8QI 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 EP53A8xQI converters are a complete power system on chip or 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 a 0603 input capacitor and a 0805 output capacitor. • Pads are available to add up to one additional input capacitor and one additional output capacitor for evaluation of performance over a wide range of input/output capacitor combinations. • Pads are available to populate an external voltage divider (for feedback) if desired. The pads are labeled R1 and R2. Pads are also available for placing an optional feed-forward capacitor (labeled C9) across resistor R1 to modify the compensation. • 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.
