A capacitor to GND on the CT pin sets the slew rate, and the higher the Capacitor the higher the slew rate. Rise times are shown below.The following equation can be used to estimate the rise time for different VIN and CT capacitors:

tR = (0.3418VIN + 0.1036) × CT + 14.064VIN + 12.255

where

  • tR = Rise time in µs.
  • VIN = Input voltage in V.
  • CT = CT Capacitor in pF.
