7 Summary

Bode plots are measurable for DCAP, D-CAP2, and D-CAP3 converters. With the technique provided, Bode plots can be measured to make sure of the system stability and to serve as a guideline to optimize load transient performance. To obtain a trustworthy Bode plot result that provides confidence about your system, take some precautionary setup steps to minimize errors.
