Printed Circuit Board Layout Sugges-
tions
The EL driver's high-frequency operation makes
PCB layout important for minimizing electrical
noise. Keep the IC's GND pin and the ground
leads of C1 and C
less than 0.2in (5mm) apart.
Also keep the connections to the COIL pin as
short as possible. To maximize output power
and efficiency and minimize output ripple volt-
age, use a ground plane and solder the IC's VSS
pin directly to the ground plane.
EL Lamp Driver Design Challenges
There are many
variables which can be opti-
mized for specific applications. The amount of
light emitted is a function of the voltage applied
to the lamp, the frequency at which is applied,
the lamp material, the lamp size, and the induc-
tor used. Sipex supplies characterization charts
to aid the designer in selecting the optimum
circuit configuration.
Sipex will perform customer application evalu-
ations, using the customer's actual EL lamp to
determine the optimum operating conditions for
specific applications. For customers consider-
ing an EL backlighting solution for the first
time, Sipex is able to provide retrofits to non-
backlit products for a thorough electrical and
cosmetic evaluation. Please contact your local
Sipex sales Representative or the Sipex factory
directly to initiate this valuable service.
