Notes:
3. Production testing of the device is performed at 25°C. Functional operation of the device and parameters specified over a -40°C to +105°C
temperature range, are guaranteed by design, characterization and process control.
4. 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.
