Bill of material

Another inductor has been tested on this platform. Better results in terms of efficiency were

achieved thanks to a lower DC resistance. For mechanical space reasons these inductors

have not been used in the power stage.

For any efficiency tests consider also the MURATA power inductor with 1.5 mH up to 1.3 A

(1415513C).
