There was recent thread (which I can no longer find) in which these regulators were mentioned but the cost was high.
Just noted the RECOM site where the prices are much less than was discussed then.

and

These are claimed at up to 97% efficiency so could be the answer to that high volt drop DC - DC regulator issue.
