9.1 Application Information

The LMZ10503EXT is a step-down DC-to-DC power module. 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 LMZ10503EXT. 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. Visit www.ti.com for more details. Note that the low radiated emissions (EMI) are tested under the EN55022 Class B standard (EN 55022:2006, +A1:2007, FCC Part 15 Subpart B: 2007). See Table 9 and Layout for information on the device under test.
