10.2.3 Application Performance Plots
The below oscilloscope captures show the difference between the inrush current for CT = 0 pF and CT = 1000 pF settings. The CT = 1000 pF setting is able to keep the inrush current under the required 200 mA, while the CT = 0 pF setting is too fast for this design.
