LM73606-Q1: Datasheet Error of Cout Calculation

Part Number: LM73606-Q1
Other Parts Discussed in Thread: LM63635-Q1, , LMR33630-Q1

Hello DC/DC Team,

The customer is considering to use either LM73606-Q1 or LM63635-Q1.
In the datasheet, both devices have example formula how to calculate the Cout.
The formula looks same, however the definition is different and we believe the description of LM73606-Q1 is wrong...

★In case of LM73606-Q1 : Iout (load current)

★In case of LM63635-Q1 : ΔIout(output current transient)

If the Iout=Load current, Fsw=400kHz requires more than 100uF capacitance. (It's too much large!)
As I glance the datasheet of LMR140x0, I believe ΔIout(output current transient) is correct.
