2. Note: It is not recommended to operate the current sources at minimum duty cycle with low LED currents.

3. The dcdc output voltage VOUT is regulated to 150mV above the maximum LED voltage (LED1...LED5) to guar-

antee proper operation of the current with output voltage ripple and undershoots (e.g. due to PWM or supply

voltage changes)

4. The short LED detection debounce time is longer than the open LED detection debounce time to allow the par-

asitic capacitance of the LED to charge above VLED_SHORT within this time and avoid wrong triggering of short

LED detection.
