SP4428 Datasheet, PDF (5/11 Pages) Sipex Corporation – Electroluminescent Lamp Driver High Drive Capability for Low Voltage Applications

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).
