PRODUCTION DATA.
this example uses a 1-A solution with 45% inductor ripple. Set ΔIL-PP = 0.45A
where
When selecting an inductor ensure the ratings for both peak and average current are adequate. It is best to select an inductance value of at least the calculated value or higher. For example, most cases use 56 µH or 68 µH given the 52 µH calculation. However, in this example size and efficiency are a concern and the application allows for the use of an output capacitor. Because a value of 52 µH not close to any common values, and output capacitance is allowed, 47 µH is selected. 47 µH has a lower winding resistance (DCR) for the same case size.
