designer with a vastly superior display

brightness range. This brightness range is

achievable with virtually any LCD display.

externally programmable over a range of 5

to 6.5mA in 0.5mA steps to allow the

inverter to properly match to a wide array

of LCD panel lamp current specifications.

The modules include a dimming input that

permits brightness control from a dc

voltage source, a PWM signal or an

external potentiometer.

Technique provides flicker-free brightness

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

dimming application.
