SP4428 Electroluminescent Lamp Driver

Electroluminescent backlighting is ideal when used

with LCD displays, keypads, or other backlit

readouts. Its main use is to illuminate displays in

dim to dark conditions for momentary periods of

time. EL lamps typically consume less than LEDs

or bulbs making them ideal for battery powered

products. Also, EL lamps are able to evenly light

an area without creating "hot spots" in the display.

The amount of light emitted is a function of the

voltage applied to the lamp, the frequency at which

it is applied, the lamp material used and its

size. There are many variables which can be

optimized for specific applications. Sipex supplies

characterization charts to aid the designer in

selecting the optimum circuit configuration

(see page 6 and 7).
