UCD3138ALLCEVM150: Sizing of output DC capacitor bank

Part Number: UCD3138ALLCEVM150


With reference to UCD3138ALLCEVM150 schematic, there are a few SMD MLCC capacitors placed as a part of the capacitor bank.

Can you please clarify the role of these MLCC capacitors (C50, C53, C54, C55, C68) that are present in addition to the electrolytic capacitors?

If so, please put forward the specific requirement regarding selection of these MLCC capacitors at the output side?
