PRODUCTION DATA.
Set the nominal inductor ripple current (ΔiL-PP) by solving for the appropriate inductor (L1):
Buck
Boost and Buck-boost
To set the worst case inductor ripple current, use VIN-MAX and DMIN when solving for L1.
The minimum allowable inductor RMS current rating (IL-RMS) can be calculated as:
Buck
