Considering the overall WW application scenario, there is a direct correspondence between

Typical configurations A/B and regulation curve Vreg-1, and between typical configuration C

and regulation curves Vreg-2 and Vreg-3. This is allowing the summary of all possible

customization for L9911 in the table below.
