8.3.2.1 Programmable Soft-Start (NR/SS)
Soft-start directly controls the output start-up time and indirectly controls the output current during start up (inrush current).
Figure 8-2 shows that the external capacitor at the NR/SS pin (CNR/SS) sets the output start-up time by setting the rise time of the internal reference (VNR/SS).
