NOTES:
8. Parameters with MIN and/or MAX limits are 100% tested at +25°C, unless otherwise specified. Temperature limits established
by characterization and are not production tested.
9. Independent from the numbers of LEDs, at minimum VIN of 4.5V, maximum VOUT is limited to 35V. And at maximum VIN of 26.5V,
minimum VOUT is limited 28V.
10. Limits established by characterization and are not production tested.
11. Varies within range specified by VHEADROOM_RANGE.
