Initial set position of the enable switch
This demo board is designed to have two LGA50D modules which can be tested
independently with 2 independent input supplies.
However, if the user wants to use one input (either Vin1 or Vin2) to power both modules,
then this can be done by linking the 2 solder pads together as identified in the picture
below:
Fig. 8 – Shorted pads required to use a single input to supply both LGA50D modules
The short should be removed for efficiency test, because it effects the test result.
