Buck-boost, 3v to 6.4v in, white LED drive out, 3A, how to handle the high end of Vin with a buck-boost

I need to run a while LED (output voltage range from 2.5-4.5v 4A surge, 3A steady state) from a battery source that can range from 3v to 6.4v in. So it's a buck-boost. I haven't been able to find a buck-boost that has a Vin higher than 5, with an abs...

I believe there is an error in AN5114 Section 3.3.1 where R1+R2 is calculated: seems like the V_photo term was disregarded. Was there then higher ripple measured across the TRIAC than was expected?

Hello, dear colleagues! I didn't find any references to the marking and datecode of the LD1117S12CTR component in the documentation.

The first question is: does the LD12 label correspond to the LD1117S12CTR part number? The second question F928 is a datacode? If so, what date is indicated here?
