Notes:
9. Static current of device is approximately 700 μA, see Graph, Page 16
10. 100% brightness corresponds to V ADJ = V ADJ(nom) = V REF . Driving the ADJ pin above V REF will increase the V SENSE threshold and output current
proportionally.
11. Ratio of maximum brightness to minimum brightness before shutdown V REF = 1.25/0.3. V REF externally driven to 2.5V, ratio 10:1 .
