STEVAL-STPM801 inductor values ? (L2 and L4)
Both the BoM and Schematic (in the Data Brief) do not show the part numbers or values for L2 and L4 on the STEVAL-STPM801 ORing circuit. Which inductors are used on the reference design? Thank you.

Your question has already been answered directly, but here is a summary for other readers who are also looking for an answer to the same question.:
L2 and L4 are not populated on the eval board and therefore not included in the BOM. They are the inductors for optional low‑pass PI filters.
If a front‑end filter is required, you can choose the PI components for the desired cutoff frequency and impedance; the inductor must be rated for the maximum system current.
