The inductor is selected to meet the recommended 30% peak-to-peak inductor ripple specification:
Equation 30. ![GUID-3DDF727B-3209-4891-81DF-FC9701D27904-low.gif](/ods/images/SLUSD66D/GUID-3DDF727B-3209-4891-81DF-FC9701D27904-low.gif)
The closest standard capacitor is 68 µH.
- Lower inductor values increase the peak-to-peak inductor current, which minimizes size and cost at the expense of reduced efficiency and larger output capacitor.
- Higher inductance values decrease the peak-to-peak inductor current, which increases efficiency but reduces the operating range based on minimum sense voltage ripple, ΔV(CSP-CSN) specification.
