8.1 Application Information

The LM5007 requires only a few external components to convert from a wide range of supply voltages to a fixed output voltage. To expedite and streamline the process of designing a LM5007-based converter, a comprehensive LM5007 quick-start calculator is available for download to assist the designer with component selection for a given application. WEBENCH® online software is also available to generate complete designs, leveraging iterative design procedures and access to comprehensive component databases. The following sections discuss a design procedure using a typical application example. Figure 7 shows the LM5007 in a configuration suitable for several application use cases. See the LM5007 EVM for more details.
