EVB-EN5311QI: 0.8 ~ 3.3V @ 1A, 2.4 ~ 5.5V in

Summary

The Enpirion EN5311QI-E DC-DC Converter module evaluation board is provided for evaluating a new class of DCDC converter product, a complete power system on silicon. The EN5311QI 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 a 0805 4.7 uF input capacitor and a 0805 10 uF 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 also available to populate an external divider if desired.

Easy jumpers are provided for the following signals: enable, 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.
