Note (1) The power supply capacity should be higher than the total converter power consumption PBL. Since
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 converter dimming.
Note (2) The measurement condition of Max. value is based on 42" backlight unit under input voltage 24V,
average LED current 120 mA and lighting 1 hour later.
Note (3) The duration of rush current is about 30ms. Even though Inrush current is over the specified value,
there is no problem if I2T of fuse Spec is satisfied.
Note (4) 5% minimum duty ratio is only valid for electrical operation.
