Input Inrush Current
An NTC limits the input inrush current after turn-on of the input voltage. The
inrush current is input voltage and ambient temperature dependent. The
output load has no impact on the inrush current value.
The charging current into EMI suppression capacitors is disregarded in the
first microseconds after switch-on.
