Note (3) The power supply capacity should be higher than the total Converter power consumption Pin. Since
the dimming mode was applied for LED backlight, the driving current changed as dimming duty on
and off. The transient response of power supply should be considered for the changing loading
when Converter dimming.
Note (4) The measurement condition of Max. value is based on 52" backlight unit under input voltage 120V
and lighting 1 minute/ 3 hours later.
