Overcurrent protection (OCP)
In normal operation the HS MOS is turned off when the sensed current is equal to programmed current (refer to
Figure 2). The maximum available current is limited by the internal OCP (overcurrent protection) comparator,
cycle by cycle. The IPK threshold is gradually reduced during the switching period by slope contribution, as shown
in Figure 18.

The inductor current is also monitored during LS MOS on-time. This feature, also known as “valley current
limitation”, is effective in case of current runaway due to HS MOS minimum on-time limitation and very low
VOUT / VIN ratio. This protection can avoid the HS MOS turn-on if the inductor current, sensed during LS MOS
on-time, is higher than the IVY threshold (Figure 19).
