AN-1197Selecting Inductors for Buck Converters Selecting Inductors for Buck Converters Introduction This Application Note provides design information to help select an off-the-shelf inductor for any continuous-mode buck converter application. The first part shows how the designer should estimate his requirements, specifically the required inductance. The next part takes an off-the-shelf inductor and shows how to interpret the specs provided by the vendor in greater detail. A step-by-step procedure is provided. Finally, all the previous steps are consolidated in a single design table, which answers the question: “How will the selected inductor actually perform in a specific application?” The important point to note here is that though every inductor is designed assuming certain specific ‘design c……
