Table 3. ELECTRICAL CHARACTERISTICS (Continue)

Notes :

1. Electrical characteristics are determined after the unit has been ‘ON’ and stable for approximately 60

minutes at 25± 2°C. The specified current and power consumption are under the typical supply Input voltage

24Vand VBR (ExtVBR-B : 100%), it is total power consumption.

2. The life time (MTTF) is determined as the time which luminance of the LED is 50% compared to that of initial

value at the typical LED current (ExtVBR-B :100%) on condition of continuous operating in LCM state at

25± 2°C.

3. LGD recommend that the PWM freq. is synchronized with One time harmonic of V_sync signal of system.

Though PWM frequency is over 120Hz (max 252Hz), function of LED Driver is not affected.

4. The duration of rush current is about 200ms. This duration is applied to LED on time.

5. Even though inrush current is over the specified value, there is no problem if I2T spec of fuse is satisfied.

6. ExtV

BR-B signal have to input available duty range and sequence.

After Driver ON signal is applied, ExtV

BR-B should be sustained from 5% to 100% more than 500ms.

After that, ExtV

BR-B 1% and 100% is possible

For more information, please see 3-6-2. Sequence for LED Driver.
