designer with a vastly 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 or

a PWM signal or external potentiometer.

The maximum output current is externally

programmable over a range of 5mA to

6.5mA in 0.5mA steps to allow the

inverter to properly match to a wide array

of LCD panel lamp current specifications.

Technique provides flicker-free brightness

control in any wide range typically (50:1+)

dimming application.
