inductor with low DC resistance is size and cost. To
lower the resistance, larger wire is used to wind the

approximately 0.5 ? . Inductors with DC resistance
lower than 0.1 ? will not have a significant impact on the
efficiency of the converter.
5.3 L and C OUT Combinations
When selecting the L-C OUT output filter components,
the inductor value range is limited from 10 μH to 22 μH.
However, when using the larger inductor values, larger
capacitor values should be used. The following table
lists the recommended combinations of L and C OUT .
