Hi.
I would make my own driver with TPS63020 too. Now i have problem with PCB, but on the net I found this: http://focus.ti.com/lit/ug/slva268/slva268.pdf
and this Re: TPS63020 for constant current LED Driving - Non-Isolated DC/DC Forum - Non-Isolated DC/DC - TI E2E Community
Maybe it will be useful for you :)
I would make 3A driver for Cree XM-L LED with PWM control.

I have yet to get the TPS63020 to go above 500mA at 4V ... I think XM-L T6 need more than 4V just as 445nm diodes. Plus these IC are f*ing expensive ... not worth it when we have a very nice 2.8A driver available for $12USD: http://www.kaidomain.com/ProductDetails.aspx?ProductId=1866

Cree XM-L need 2,9-3,3V so it´s OK.

Driver on KD is nice, but it´s for 2 li-ion :/

Can't wait to see those boost drivers when/if you finish them

maybe you should offer testload kits and finished versions, what do you think?
