designer with a vastly superior display

brightness range then typical with analog

(amplitude control) dimming.

that permits brightness control from either

a DC voltage source or a PWM signal or

external Potentiometer.

output current is externally programmable

over a range of 5 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.
