Internal resistance extension (option)
With an optional internal resistance extension, the same pin definition
and specification values apply.
For the power limit the specification is inverted!
In the case the power limit input voltage P
REF
= 0 V, there will not be
any limiting of the maximum power, i.e. the power limit is set to the (full)
nominal power. Conversely, the power limit is set correspondingly on
operation via pin 14 (P
REF
).
