Maximum Duty-cycle limitation
The device limits the maximum duty cycle and this value is not fixed but it depends on the
delivered current given by the following relationship:
From the previous relationships the maximum duty cycle results:
If the desired output characteristic crosses the limited-D
output resulting voltage will start to drop after the cross-point. In this case the output voltage
starts to decrease following the resulting characteristic (dotted in
