8.1 Application Information

The LM3102 is a step-down DC-to-DC controller. It is typically used to convert a higher DC voltage to a lower DC voltage with a maximum output current of 2.5 A. The following design procedure can be used to select components for the LM3102. Alternately, the WEBENCH software may be used to generate complete designs.

When generating a design, the WEBENCH® software uses iterative design procedure and accesses comprehensive databases of components. For more details, go to www.ti.com.
