The intersection of the Load Current and the Volt-microseconds lines on the chart below will determine which

inductors are capable for use in the design. Figure 16 shows a sample of parts that can be used. The offline

calculator tools and WEBENCH will fully calculate the requirements for the components needed for the

design.
