Stability is an important factor in the system when adding more output capacitance. The general rule of thumb for a stable design is a desired phase margin (PM) of at least 45° or greater realized at the 0dB of loop gain. In extreme conditions too much output capacitance added to the system may result in a lowered bandwidth and slower transient response. Table 3-1 shows the PM for each output voltage selection measured from a TPSM63610EVM modified for inverting buck boost application using the default bill-of-material which can be found in TPSM63610 36-V, 8-A Buck Regulator Evaluation Module User's Guide. For other application conditions, it is recommended to design and verify proper stability using a frequency analyzer, refer to Working With Inverting Buck-Boost Converters, application note (figure 4-2) for setup.
