7.1 Application Information

The LMZ22005 is a step-down DC-to-DC power module. The device is typically used to convert a higher DC voltage to a lower DC voltage with a maximum output current of 5 A. The following design procedure can be used to select components for the LMZ22005. Alternately, the WEBENCH software can be used to generate complete designs.

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