Shown in Figure 5. is the discontinuous inductor
current. The ramp-up current stores energy in the
inductor. The switching transistor,Q1, is on during this
time and has an equivalent current ramp-up, shown in
Figure 6. The ramp-down current is associated with
the energy being delivered to the output via the
Schottky diode, D1. The diode current is equivalent to
this ramp-down current and is shown in figure 7.
