3.0 A, Step-Down Switching Regulator The LM2596 regulator is monolithic integrated circuit ideally suited for easy and convenient design of a step−down switching regulator (buck converter). It is capable of driving a 3.0 A load with excellent line and load regulation. This device is available in adjustable output. Live from new york arcata.

I want to clarify the statement on. It states one of its feature is Ensured 3A Output Load Current. Torrent crack for en route.

My question is related to the Adjustable version of LM2596 Vin: 4.5V-40V Vout: 3.3V-37V Does the above statement means: No matter what voltage the input is (as long it is still in Vin range and higher than Vout), the LM2596 will still regulate with 3A output load current? Extreme cases: Vin: 40V and Vout: 3.3V, and Vin: 40V and Vout: 37V Can LM2596 regulate both cases with 3A output load current? If not, please provide me info or chart that show varying load current based on Vin and Vout. Side notes: My reason to ask these question is because I think LM2596 should have max power rating (I can't find one yet from Datasheet), thus 37V@3A would be more than 100W. And I think the power is too big for such small IC. Thanks for your time!
