Direct Drive architecture includes two load feedback control loops to
provide uncompromised CCFL ignition and operation characteristics.
Lamp current is regulated in the CCFL return lead (I
loop) to insure
constant light output with changing lamp parameters and power supply
voltage. This also allows accurate and repeatable brightness control.
Dimming ratio with the LX1620 analog dimming inverters is typically 6:1
when driving dual LCD lamp panels.
If no current flows in the CCFL return path because of an unstruck or

failed lamp, the inverter applies full strike voltage potential. The output
voltage feedback loop (V
) takes control and regulates output voltage to
1650V
. This insures the lamp will ignite under worst case temperature
and aging conditions.
Because output voltage is actively regulated, it will never exceed
component and panel insulation ratings. This prevents destructive corona
discharge to insure long term reliability of the system.
