Thanks. Yes I’m aware that the output current is different than the input. I was just surprised how much marketing they put into this. Lol.
Well, you were asking why the discrepancy... I didn't know whether this was a genuine technical question or more of a rhetorical one, so I took the technical path.
Sure this is marketing. OTOH, technical documents and technical marketing are difficult tasks.
For such converters, the only real figure that would make sense would be the max switching current IMO (and maybe any additional internal current limiting feature). But it would not make it immediately obvious what to expect in terms of the max output current, which is a figure that most designers are interested in when selecting a switching converter.
If you only mention switching current figures in a datasheet, many people will complain that it's even more "marketingly" misleading - given that it will always be greater - than giving a typical max output current (in a typical use case), even if obviously the typical use case chosen may not be your use case at all. And it still kind of helps while roughly selecting models.
Guess what, people always complain.

And of course, moral is that you should always read datasheets and not simply rely on titles and headlines.
