7.3.12 Soft-Start (SS/TR)

Leaving SS/TR pin open enables the internal slow start time interval of approximately 4.1 ms. Adding additional capacitance between the SS pin and AGND increases the slow start time. Increasing the slow start time will reduce inrush current seen by the input source and reduce the current seen by the device when charging the output capacitors. To avoid the activation of current limit and ensure proper start-up, the SS capacitor may need to be increased when operating near the maximum output capacitance limit.

See Table 11 below for SS capacitor values and timing interval.
