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

8mA in 1mA 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.
