9.2.4.5 Soft Start Time

The soft start time is configured using the CSS capacitor. In order to calculate the value of the capacitor, the VOUT slew rate needs to be calculated using Equation 3 to make sure the maximum VOUT slew rate requirement shown in Equation 4 is satisfied. This requirement is particularly important for space applications where large output capacitance is typically used, which translates to a lower maximum allowable VOUT slew rate. For this particular design, the VOUT slew rate is 555 V/s which is less than the maximum VOUT slew rate of 882 V/s, meeting the requirement from Equation 4. Now, the soft start capacitor value can be calculated as 117 nF using Equation 6, since VIN = 5 V for this application.
