In most of the overcurrent conditions, the conduction time of the high-side switch is higher than the masking time
and so the peak current protection limits the switch current.

The DC current flowing in the load in overcurrent condition is:
IDCOUT=IMAX−IRIPPLEVOUT
2 =IMAX− VIN− VOUT

The Figure 20. Soft-start procedure with VOUT shorted to GND shows the L6983 soft-start procedure with VOUT
shorted to GND.
Figure 20. Soft-start procedure with VOUT shorted to GND
The Figure 21. Over current procedure with persistent short circuit between VOUT and GND shows the L6983 over
current protection with a persistent short circuit between VOUT and GND.
