Note (2) At 20k Hz PWM control frequency，duty ratio range is restricted from 20% to 100%.
Note (3) The lifetime of LED is defined as the time when it continues to operate under the conditions at
Ta = 25 ±2 ℃ and Duty 100% until the brightness becomes ≦ 50% of its original value. Operating
LED under high temperature environment will reduce life time and lead to color shift.
