For 100% brightness either leave floating or connect to 1.25V relative to GND.
For most applications the LED current will be within 8% over the duty cycle range specified. Duty cycle accuracy is also dependent on propagation
delay. Smaller size inductors can be used but LED current accuracy may be greater than 8% at extremes of duty cycle. This is most noticeable at low
duty cycles (less than 0.1) or when the input voltage is high and only one LED is being driven.

5. Test condition for SO-8, MSOP-8 and U-DFN3030-10: Device mounted on FR-4 PCB, 2”x 2”, 2oz copper, minimum recommended pad layout on
top layer and thermal vias to bottom layer ground plane. For better thermal performance, larger copper pad for heat-sink is needed.
