hello all
i am having 28v 6A source and i want to convert it to 5v 2A
pls help me with some suggestions
thanks in advance
As your title shows, you have already considered the most logical solution. A DC to DC converter, and in particular a buck converter, would seem to work well. You might see 85 percent power conversion efficiency.

For the sake of completeness, you could also use linear regulation techniques, but the efficiency would only be 15 percent and getting rid of that heat is a problem.

Your post is very vague. Are you trying to buy or build your solution? You should be able to buy a 24 V to 5 V buck converter off the shelf. Most of these will work with 28 V in.
