        4 The V signal drops simultaneously with the output voltage. If
        the pull-up resistor
        RP is connected to Vo1+. The V signal
        remains high if
        RP is connected to an external source.
        Options B1/B2: Cooling Plate
        Where a cooling surface is available, we recommend the use
        of a cooling plate (option B1) instead of the standard heat sink.
        The mounting system should ensure sufficient cooling
        capacity to guarantee that the maximum case temperature
        TC max is not exceeded. The cooling capacity is calculated by:
        (100% –
        η)
        PLoss = –––––––––– Vo Io
