Notes:
6. Static current of device is approximately 700 μA, see Graph, Page 17.
7. 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.
8. Ratio of maximum brightness to minimum brightness before shutdown V REF =1.25/0.25. V REF externally driven to 2.5V, ratio 10.1.
