Output Voltage Ripple

Figure 3-5 to Figure 3-8 show the output voltage ripple. The images are taken at 12-V input, –0.2-V and –0.6-V outputs both at no load and 15-A load conditions. The waveforms were captured with infinite persistence being enabled and measurements were made for the peak-to-peak, mean, and RMS values of the output voltage ripple.
