8.3.7 Soft Start and Recovery from Dropout

When designing with the LMR3650x, both soft start and recovery from dropout can cause slow rise in output voltage and must be considered as a two separate operating conditions, as shown in Figure 8-6 and Figure 8-7. These features ramp the output voltage at a controlled rate, keeping the output voltage from overshooting. See Section 8.3.7.1 and Section 8.3.7.2 for more details.
