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 10 to 16mA (per lamp pair)

in 2mA 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.
