I just spotted this chip.

If you are looking to power a Luxeon from a Li ion cell, this could be the one for you.

Buck-boost operation, output current regulation a 4.7uH industor.

Vin is 2.7 to 5.5V

I think this has been pointed out here before, you must remember effiency is only part of the equation. 100% effiency wouldn't be much good if you have 0% light coming out.

I have some samples of this chip but it's package is similar to the LT1618 which is fragile and very delicate to work with.
