8.1 Application Information

The LMR16030 is a step down DC-to-DC regulator. It is typically used to convert a higher DC voltage to a lower DC voltage with a maximum output current of 3 A. The following design procedure can be used to select components for the LMR16030. This section presents a simplified discussion of the design process.
