8.1 Application Information

LM5008A 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 LM5008A-based converter, a comprehensive LM5008A Quick-Start tool 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 10 shows the LM5008A in a configuration suitable for several application use cases. See the LM5008A EVM for more details.
