ZXSC100

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.
