The SS/TRK pin can be floating to start up following the internal soft-start ramp. In order to extend the soft-start time, an external soft-start capacitor can be used. Use Equation 12 in order to calculate the soft-start capacitor value.
With a desired soft-start time tSS = 11 ms, a soft-start charging current of ISSC = 2 μA (typical), and VFB = 1.006 V (typical), Equation 12 yields a soft-start capacitor value of 22 nF.
