brightness range than typical with analog

(current 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 match properly 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.
