TI’s customers are responsible for determining suitability of components for their purposes. Customers should validate and test their design implementation to confirm system functionality. 9.1 Application Information The LM5181-Q1 requires only a few external components to convert from a wide range of supply voltages to one or more isolated output rails. To expedite and streamline the process of designing of a LM5181-Q1-based converter, a comprehensive LM5181-Q1 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 the design procedure for both single- and dual-output implementations using specific circuit design examples. As mentioned previously, the LM5181-Q1 also integrates several optional features to meet system design requirements, including precision enable, input UVLO, programmable soft start, output voltage thermal compensation, and external bias supply connection. Each application incorporates these features as needed for a more comprehensive design. The application circuits detailed in the Typical Applications show LM5181-Q1 configuration options suitable for several application use cases. 9.2 Typical Applications For step-by-step design procedures, circuit schematics, bill of materials, PCB files, simulation and test results of LM5181-powered implementations, refer to the TI reference designs library. 9.2.1 Design 1: Wide VIN, Low IQ PSR Flyback Converter Rated at 5 V, 0.5 A The schematic diagram of a 5-V, 0.5-A PSR flyback converter is given in Figure 21.
