Hi All,
The Fenix P1 has one of the most efficient constant current driver circuits available today. It does a great job of maintaining constant brightness for an impressive amount of time on a single cell.
Has anyone discovered what IC the P1 uses? It is an SOT23-6 package. A product search using the input voltage and output voltage narrows the selection to a handfull of IC's.
The inductor plays a big part in the equation, too. But with a bit of testing (with a much better meter than I have) it shouldn't be too hard to determine that inductor value. With the correct value, and the inductor size/package type, the selection should be narrowed down quite a bit.
I have just started my research on the subject. But, before I invest too much time in my pursuit of answers, I thought that I would ask here.
Thanks,
