TPS1663: Output capacitance COUT problem

Part Number: TPS1663
Other Parts Discussed in Thread: LM5145

Hi Dear,

The System Power input is 24V-55V,Considering the need for hot plugging,Oue Customers use efuse TPS1663  to put it on the front of LM5145 for hot-swap protection.

See TPS1663 evaluation board circuit, output pin has a 1000uf electrolytic capacitor.

What is the function of this electrolytic capacitor?

How is the COUT capacitance calculated?and whether it can be removed?
