of the minimum conduction time of the power element. If the hiccup current level (6.2 A
typical) is triggered, the switching activity is prevented for 12 cycles.
Figure 18 shows the operation of the constant current protection when a short-circuit is
applied at the output at the maximum input voltage.

During pulse skipping, high side OFF, low side keeps ON till 26clks finish (13clks for
LED2001) or Ipk decreases to be zero value.
