Figure 2 shows the output voltage ripple, the SW node, and the inductor current during discontinuous-

current operation of the TLV61220. The measurements are done with 1.2-V input voltage, 1.8-V output

voltage, and 10-mA load.

Figure 3 shows the output voltage, the SW node voltage, enable, and the inductor current during start-up

using enable of the TLV61220. The measurements are done with 0.7-V input voltage, 1.8-V output

voltage, and 12-mA load.
