Board description
11.1.1
Power input (VIN)
This is the input voltage for the power conversion. The high-side MOSFET drain is
connected to this input. Supply must be compliant with VIN recommended operating
conditions and capacitors rating.
If VIN voltage is compliant also to VCC range listed in recommended operating conditions, it
can supply also the device through R16 resistor.
