Building FPGA board

Hello,

in case of not knowing how and why with switched-mode power supply, I recommend using the National WEBENCH tools. You define input and output parameters and they tell you which parts to use. You can simply follow the design recommendation and don't need to ask "could I use a resistor instead of an inductor" or "should this pin connected anywhere else".:D

For a first evaluation, I would generally recommend to use linear voltage regulators as far as possible, but I understood from previous forum discussions that you are targetting a battery powered application.

Another possibility would be to copy an existing evaluation board's power supply. As an advantage you can do comparative measurements if your designs behaves unexpected.

By the way, I wouldn't expect power supply to be biggest challenge when creating a new board.

Best reagards and happy developping,

Frank
