Note 2: Measurement condition Rising time = 20ms (VDDB : 10%~90%);
Note 3: When BLU off ( VDDB = 24V , VBLON = 0V) , IDDB (max) = 0.02A
Note 4: V_DIM voltage of 100% duty ratio =3.1V~3.3V means Burst Mode entry point should be located between
3.1V and 3.3V.
Note 5: Less than 5% dimming control is functional well and no backlight shutdown happened
Note 6: Normal : 0~0.8V ; Abnormal : Open collector
