7.3.2.1 Programmable Soft Start (NR/SS Pin)
Soft start directly controls the output start-up time and indirectly controls the output current during start-up (inrush current).
The external capacitor at the NR/SS pin (CNR/SS), as shown in Figure 40, sets the output start-up time by setting the rise time of the internal reference (VNR/SS).
