MAX25239/MAX25240 Crossover Frequency Selection

Question

Accepted Answer

Question: How to determine and calculate the MAX25239/MAX25240 Buck-Boost Converter Crossover Frequency? 
 Answer: The crossover frequency by practice is selected to be 1/5th of the switching frequency or lower of the fzRHP (right-half-plane zero). This information can be found in the MAX20039/MAX20040 Buck-Boost Converter datasheet ("Error-Amplifier Compensation Design for the MAX20040" section) which is similar to MAX25239/MAX25240.
