Use Equation 5 to find the maximum slew rate value to limit inrush current for a given capacitance:
Once the required slew rate shown in Equation 1 can be used to find the minimum CT capacitance
To ensure an inrush current of less than 150 mA, choose a CT value greater than 594 pF. An appropriate value should be placed on such that the IMAX and IPLS specifications of the device are not violated.
