3.3 Bode Plot

Figure 3-13 provides the bode plot at VIN = 24 V, VOUT = 5 V, FSW = 1 MHz, and IOUT = 8 A. Figure 3-14 shows a typical capacitance versus voltage curve for a 47-µF, 16-V, X6S output capacitor to highlight the effective capacitance value of a ceramic. See component details in Bill of Materials.
