Product List
The easiest first step to improve this voltage deviation is to add external capacitance. The right graph demonstrates the reduction in the voltage excursion. Unfortunately, it does this at a very heavy price. Adding more capacitance results in a reduced phase margin. The lost gain bandwidth (seen in the left graph) results in an unfavorable “ringing” in the voltage caused by this reduced phase. This is inherently caused by the module’s internal compensation not being “tuned” to operate at this high level of external capacitance. Adding even more capacitance would result in instability and a non-viable design.
