Feedback Loop Compensation
Since TPS51113/TPS51163 utilizes voltage-mode control for buck converters, Type III network is recommended
for loop compensation. Suitable poles and zeros can be set by choosing proper parameters for the loop
compensation network.
To calculate loop compensation parameters, the poles and zeros for the buck converter should be obtained. The
double pole, determined by the L, and COUT of the buck converter, is located at the frequency as shown in the
following equation.
(19)
Also, the ESR zero of the buck converter can be achieved.
(20)
Figure 8 shows the configuration of Type III compensation. The transfer function of the compensator is described
in Equation 21. Also, poles and zeros for the Type III network are shown in Equation 22 through Equation 26.
