9.2.3 Application Curves

Figure 38 shows a test example of soft-start when driving a big capacitive load. Figure 39 shows an expanded waveform of the output current.

Load current = 0.2 A	CH2 = FAULT	INx = ↑
Current limit = 0.5 A	CH3 = output voltage	CH1 = INx
CL = 2.3 mF	CH4 = output current	VS = 12 V
