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 39" backlight unit under input voltage 24V, at 2D/3D
Mode and lighting 1 hour later.
Note (3) For input inrush current measure, the VBL rising time from 10% to 90% is about 20ms.
Note (4) EPWM signal have to input available duty range. Between 97% and 100% duty (DDR) have to be avoided.
(97% < DDR < 100%) But 100% duty(DDR) is possible. 5% duty (DDR) is only valid for electrical operation.
Note (5) FB and DDR are available only at 2D Mode.
Note (6) Below diagram is only for power supply design reference.
