The peak-to-peak inductor current ripple is:

EQUATION 4-4:

The MIC45116 has a 1.0 µH inductor integrated into

the module. In case of a hard short, the short limit is

folded down to allow an indefinite hard short on the

output without any destructive effect. It is mandatory to

make sure that the inductor current used to charge the

output capacitance during soft-start is under the folded

short limit; otherwise the supply will go in hiccup mode

and may not finish the soft-start successfully.

With R26 = 1.62 kΩ and C16 = 15 pF, the typical output

current limit is 8A.
