Note (1) Lamp current is measured by utilizing AC current probe.

Note (2) The lamp starting voltage V

should be applied to the lamp for more than 1 second after startup.

S

Otherwise the lamp may not be turned on.

Note (3) The lamp frequency may produce interference with horizontal synchronous frequency of the

display input signals, and it may result in line flow on the display. In order to avoid interference, the

lamp frequency should be detached from the horizontal synchronous frequency and its harmonics

as far as possible.

Note (4) The life time of a lamp is defined as when the brightness is larger than 50% of its original value and

the effective discharge length is longer than 80% of its original length (Effective discharge length is

defined as an area that has equal to or more than 70% brightness compared to the brightness at the

center point of lamp.) as the time in which it continues to operate under the condition at Ta = 25

±2 and Iк

Note (5) The power supply capacity should be higher than the total inverter power consumption P

= 9.0~ 10.0mArms.

L

. Since

BL

the pulse width modulation (PWM) mode was applied for backlight dimming, the driving current

changed as PWM duty on and off. The transient response of power supply should be considered for

the changing loading when inverter dimming.

Note (6) The measurement condition of Max. value is based on 42" backlight unit under input voltage 24V,

average lamp current 9.8 mA and lighting 30 minutes later.

Note (7) The duration of Input Inrush Current is about VBL Rising Time 30ms.

Note (1) The Dimming signal should be valid before backlight turns on by BLON signal. It is inhibited to

change the internal/external PWM signal during backlight turn on period.

Note (2) The power sequence and control signal timing are shown in the following figure. For a certain

reason, the converter has a possibility to be damaged with wrong power sequence and control

signal timing.

Note (3) While system is turned ON or OFF, the power sequences must follow as below descriptions:

Turn ON sequence: VBL Ш PWM signal Ш BLON

Turn OFF sequence: BLOFF Ш PWM signal Ш VBL
