Notes:
1. 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.
2. 100% brightness corresponds to VADJ = VADJ(nom) = VREF. Driving the ADJ pin above V REF will increase the VSENSE threshold and output current
proportionally.
