How to extend the input range of a linear voltage regulator?
To increase input voltage range of your supply with linear regulator you should use some step-down converter.

Thats the only reasonable method to "loose" more than 10-20V at 2A peak current. 

Correctly designed simple step-down converter will decrease voltage with little power losses and heat generation.

MAX5024 has low current because you get 6W of heat at 100mA and 60V difference between in and out pin. Thats a lot. For 2A it would be 120W :) So forget about loosing 30-60V on linear regulator with 2A current requirements. Thats insane.

There are many integrated switching regulators (like easy to use LM2574 family), but I can't find any capable to deliver 2A output with 60V input. Maybe someone will suggest something.
