5.1 Enable, Disable, and Soft Start Timing

Figure 5-1 shows the enable and disable characteristic where –VIN is –6 V, EN is toggled from ground to –2.4 V while the output drives a 1-A load. The waveform for VFB is also shown for reference. CNR_SS of 100 nF results in a soft start time of approximately 120 ms.
