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 46" backlight unit under input voltage 24V,
average LED current 84.4 mA at 2D Mode (LED current 254.4 mA
at 3D Mode) and lighting 1

Note (1) The Dimming signal should be valid before backlight turns on by BLON signal. It is inhibited to
change the external PWM signal during backlight turn on period.
Note (2) The power sequence and control signal timing are shown in the Fig.1. 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 → PWM signal → BLON
Turn OFF sequence: BLOFF → PWM signal → VBL
Note (4) When converter protective function is triggered, ERR will output open collector status.
Note (5) The EPWM interface that inserts a pull up resistor to 5V in Max Duty (100%), please refers to Fig.2.
