4. INPUT INRUSH CURRENT AND SOFT-START BEHAVIOR
Inrush current limitation
An active inrush limitation circuit (inrush limiting NTC resistor which is bypassed by a MOSFET) limits the input inrush
current after turn-on of the input voltage.
The charging current into EMI suppression capacitors is disregarded in the first microseconds after switch-on.

Soft-start function:
After the DC/DC converter is turned on, the internal output current rises slowly to its nominal value. This method
charges the output capacitors (internal and external capacitors) slowly and avoids high input currents during turn-on.
High input currents can produce a high voltage drop on the input wiring (especially with long and thin cables) which
reduces the terminal voltage on the DC/DC converter. If the terminal voltage is below the shut-down voltage, the
DC/DC converter will turn-off and will make a new start-up attempt. This effect is avoided with the integrated soft-
start function. Please note, that this function increases the rise time of the output voltage by a small amount.

All parameters are typical values at 24V, 10A, 24Vdc input voltage, 25C ambient and
after a 5 minutes run-in time unless otherwise noted.
