Hello

We have received a reference Design from the webench with the following specifications.

- Input : 10V~30V

- Output : 12V, 6A

However, we need a reduction in the number of capacitors.

Because the board size is limited.
How much can you reduce the capacitor?

Best Regards.

    Hi Louis,

    Thank you for considering the LM25118. Do you use the Webench design optimization function? When you open up the initial Webench design, on the upper left corner of the window there is a Summary box, and insider there is red color bard labeled CHANGE OPTIMIZATION, and click it an Optimization Options window will pop up, and you can chhose between the small footprint design.  See if it helps to meet your board size. 

    Thanks,
