SP4422A

Electroluminescent Lamp Driver

DESCRIPTION

The SP4422A is a high voltage output DC-AC converter that can operate from a 2.2V-5.0V
power supply. The SP4422A is capable of supplying up to 220 VPP signals, making it ideal
for driving electroluminescent lamps. The device features 50 nA (typical) standby current, for
use in low power portable products. One external inductor is required to generate the high
voltage, and one external capacitor is used to select the oscillator frequency. The SP4422A
is offered in an 8-pin narrow and 8-pin micro SOIC packages. For delivery in die form, please

THEORY OF OPERATION

The SP4422A is made up of three basic circuit
elements, an oscillator, coil, and switched H-bridge
network. The oscillator provides the device with
an on-chip clock source used to control the charge
and discharge phases for the coil and lamp. An
external capacitor connected between pins 7 and 8
allows the user to vary the oscillator frequency
from 32kHz to 400kHz. The graphs on page 6
show the relationship between C

OSC

and lamp

output voltage. In general, increasing the C

OSC

capacitor will increase the lamp output.
The suggested oscillator frequency is 90kHz

(C

OSC

=100pF). The oscillator output is internally

divided to create two internal control signals, f

COIL

and f

LAMP

. The oscillator output is internally divided
down by 8 flip flops, a 90kHz signal will be
divided into 8 frequencies; 45kHz, 22.5kHz,

11.2kHz, 5.6kHz, 2.8kHz, 1.4kHz, 703Hz, and
352Hz. The third flip flop output (8kHz) is used to
drive the coil (see figure 2 on page 9) and the
eighth flip flop output (250Hz) is used to drive the
lamp. Although the oscillator frequency can be
varied to optimize the lamp output, the ratio of
f

COIL/fLAMP

will always equal 32.

The on-chip oscillator of the SP4422A can be
overdriven with an external clock source by
removing the C

OSC

capacitor and connecting a

clock source to pin 8. The clock should have a 50%
duty cycle and range fromVDD-1V to ground. An
external clock signal may be desirable in order to
synchronize any parasitic switching noise with the
system clock. The maximum external clock
frequency that can be supplied is 400kHz.

The coil is an external component connected from
V

BATTERY

to pin 3 of the SP4422A. Energy is stored

in the coil according to the equation EL=1/2LI2,
where I is the peak current flowing in the inductor.
The current in the inductor is time dependent and
is set by the "ON" time of the coil switch: I=(VL/
L)tON, where VL is the voltage across the inductor.
At the moment the switch closes, the current in the
inductor is zero and the entire supply voltage
(minus the V

SAT

of the switch) is across the inductor.
The current in the inductor will then ramp up at a
linear rate. As the current in the inductor builds up,
the voltage across the inductor will decrease due to
the resistance of the coil and the "ON" resistance
of the switch: VL=V

BATTERY

-IRL-V

SAT

. Since the
voltage across the inductor is decreasing, the current
ramp-rate also decreases which reduces the current
in the coil at the end of tON the energy stored in the
inductor per coil cycle and therefore the light
output. The other important issue is that maximum
current (saturation current) in the coil is set by the
design and manufacturer of the coil. If the
parameters of the application such as V

BATTERY

, L,
RL or ton cause the current in the coil to increase
beyond its rated I

SAT

, excessive heat will be

generated and the power efficiency will decrease
with no additional light output. The Sipex SP4422A
is final tested using a 5mH/18Ω coil from Hitachi
Metals. For suggested coil sources see page 10.

Typical SP4422A Application Circuit

The supply VDD can range from 2.2 to 5.0V. It is not
necessary that VDD = V

BATTERY

. V

BATTERY

should not
exceed max coil current specification. The majority
of the current goes through the coil and is typically
much greater than IDD.

The f

COIL

signal controls a switch that connects the
end of the coil at pin 3 to ground or to open circuit.
The f

COIL

signal is a 94% duty cycle signal switching
at 1/8 the oscillator frequency. For a 64kHz
oscillator f

COIL

is 8kHz. During the time when the

f

COIL

signal is high, the coil is connected from

V

BATTERY

to ground and a charged magnetic field is
created in the coil. During the low part of f

COIL

, the
ground connection is switched open, the field
collapses and the energy in the inductor is forced
to flow toward the high voltage H-bridge
switches. f

COIL

will send 16 of these charge pulses

(see figure 2 on page 9) to the lamp, each pulse
increases the voltage drop across the lamp in
discrete steps. As the voltage potential approaches
its maximum, the steps become smaller (see figure
1 on page 9).

The H-bridge consists of two SCR structures that
act as high voltage switches. These two switches
control the polarity of how the lamp is charged.
The SCR switches are controlled by the f

LAMP

signal which is the oscillator frequency divided by

256. For a 64kHz oscillator, f

LAMP

=256Hz.

When the energy from the coil is released, a high
voltage spike is created triggering the SCR
switches. The direction of current flow is
determined by which SCR is enabled. One full
cycle of the H-bridge will create 16 voltage steps
from ground to 80V (typical) on pins 4 and 5 which
are 180 degrees out of phase from each other (see
figure 3 on page 9. A differential representation of
the outputs is shown in figure 4 on page 9.

Layout Considerations

The SP4422A circuit board layout must observe
careful analog precautions. For applications with
noisy voltage power supplies a 0.1µF low ESR
decoupling capacitor must be connected from V

DD

to ground. Any high voltage traces should be
isolated from any digital clock traces or enable
lines. A solid ground plane connection is strongly
recommended. All traces to the coil or to the high
voltage outputs should be kept as short as possible
to minimize capacitive coupling to digital clock
lines and to reduce EMI emissions.

Electroluminescent Technology

What is electroluminescence?

An EL lamp is basically a strip of plastic that is
coated with a phosphorous material which emits
light (fluoresces) when a high voltage (>40V)
which was first applied across it, is removed or
reversed. Long periods of DC voltages applied to
the material tend to breakdown the material and
reduce its lifetime. With these considerations in
mind, the ideal signal to drive an EL lamp is a high
voltage sine wave. Traditional approaches to

achieving this type of waveform included discrete
circuits incorporating a transformer, transistors,
and several resistors and capacitors. This approach
is large and bulky, and cannot be implemented in
most hand held equipment. Sipex now offers low
power single chip driver circuits specifically
designed to drive small to medium sized
electroluminescent panels. All that is required is
one external inductor and capacitor.

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,
and lastly, the inductor used. 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).
