compatible with variety of LCD panels

that have both lamps on one side of the

panel and use a single common lamp

return wire.

designer with a superior display brightness

range. This brightness range is achievable

with virtually any LCD display.

dimming input that permits brightness

control from either, a DC voltage source,

a PWM signal or external potentiometer.

externally programmable (through the

input connector) at either 10mA or 12mA

(5mA or 6mA per lamp). This allows the

inverter to match the panel’s lamp current

specifications, or it can be used to

purposely drive the lamps at a lower or

higher current to decrease or increase

nominal brightness. The inverter also has

a dedicated FAULT pin that indicates an

open/shorted lamp condition.
