Each Bode plot is shown at a 3.3-V output. The Bode plots for different loads exhibit similar results, with the main difference being the slight appearance of noise. Thus, one Bode plot is shown for each input voltage.

Crossover increases with load from 27 kHz at no load to 42 kHz at the maximum 60-A load, but the phase margin has a minimum of 70 degrees with a gain margin of around 10 dB.

The Bode plots in Figure 3-11 and Figure 2-6 were created at a 30-A load with Figure 3-11 having a 24-V input and Figure 2-6 having a 48-V input.
