Bulk Output Capacitance - Over Recommended per Buck/Boost Datasheet

I am wanting to use the ADP5024ACPZ IC on my next design, and want this to create a 3.3v rail.

I also want to charge up a capacitor bank, so if there is a power interrupt, I have some time to save my microcontroller info, etc.

According to the datasheet, the output capacitance max is 40uF.

What would happen if I exceed this? Would my buck/boost never reach its output voltage?

How do I achieve my goal?

Thanks!
