8.1 Application Information

The LM25011/LM25011-Q1 is a non-synchronous buck regulator designed to operate over a wide input voltage range and output current. Spreadsheet-based quick-start calculation tools and the on-line WEBENCH® software can be used to create a buck design with the bill of materials, estimated efficiency, and the complete solution cost.
