Application Information (cont.)
Soft-Start
An external capacitor from the ADJ pin to ground will provide a soft-start delay, by increasing the time taken for the voltage on this pin to rise
to the turn-on threshold and by slowing down the rate of rise of the control voltage at the input of the comparator. Adding capacitance
increases this delay by approximately 0.2ms/nF. The graph below shows the variation of soft-start time for different values of capacitor.
