2.4 Bode Plots

Each bode plot is shown at a 5VOUT output. One bode plot is shown for both input voltages of 20VIN and 48VIN. The phase margin is always at least 67.2° and gain margin is greater than 10dB. The bode plots in Figure 2-9 and Figure 2-10 were created at a full 50A load with Figure 2-10 having a 20VIN input and Figure 2-9 having a 48VIN input.
