Block Diagram of the Driver Circuitry
Theory of Operation
Electroluminescent (EL) lamps are essentially capacitors with one transparent electrode and a
special phosphor material in the dielectric. The phosphor glows when a strong AC voltage is
applied across the EL lamp electrodes. The required AC voltage is usually not present in most
systems and must be generated from a low voltage DC source. Rogers developed its patented
three-port (3P) switch-mode inverter circuit to convert the available DC supply to an optimal
drive signal for high brightness and low-noise EL lamp applications. Rogers’ 3P topology offers
the simplicity of a single DC input, single AC output, and a shared common ground that
provides an integrated EMI shielding.
The D391A IC drives the EL lamp by repeatedly pumping charge through an external inductor
with current from a DC source and discharging into the capacitance of the EL lamp load. With
each high frequency (HF) cycle the voltage on the lamp is increased. At a period specified by
the lamp frequency (LF) oscillator, the voltage on the lamp is discharged to ground and the
polarity of the inductive charging is reversed. By this means, an alternating positive and
negative voltage is developed at the single output lead of the device to one of the electrodes
of the EL lamp. The other lamp electrode is commonly connected to a ground plane, which
can then be considered as electrical shielding for any underlying circuitry in the application.
The EL driving system is divided into several parts: on-chip logic and control, on-chip high
voltage output circuitry, discharge logic circuitry, and off-chip components. The on-chip logic
controls the lamp operating frequency (LF), as well as the inductor switching frequency (HF),
and HF and LF duty cycles. These signals are combined and buffered to regulate the high
voltage output circuitry. The output circuitry handles the power through the inductor and
delivers the high voltage to the lamp. The integrated discharge logic circuit enables the lownoise functionality of this EL driver with four levels of discharge slopes on the output waveform.
The selection of off-chip components provides a degree of flexibility to accommodate various
lamp sizes, system voltages, and brightness levels. Since a key objective for EL driver systems is to
save space and cost, required off-chip components are kept to a minimum.

Designing With A D391A EL Driver IC:
I. Lamp Frequency Capacitor (CLF) Selection
Lamp Frequency (Hz)
The output frequency of the D391A EL driver is determined by the lamp frequency capacitor
(CLF) selected. Lamp frequencies of 200-500Hz are normally used. Figure 1 graphically
represents the inversely proportional relationship between the CLF capacitor value and the
oscillator frequency.

CLF (nF)
Figure 1—Typical lamp frequency vs. CLF capacitor
Alternatively, the lamp frequency may also be controlled with an external clock signal. There is
an internal frequency divider in the device so that the output lamp frequency will be onesixteenth (6.25%) of the input clock signal. For example, if a 3.2 kHz input clock signal is used the
resulting lamp frequency will be 200Hz. The clock signal input voltage should not exceed V+.
The selection of the CLF value can also affect the brightness of the EL lamp as it controls the
lamp frequency (LF). Although input voltage and lamp size can change EL lamp frequency as
well, LF mainly depends on the CLF value selected or the frequency of the input clock signal to
CLF. Figure 2 shows typical brightness of a D391A IC circuit with respect to lamp frequency. In
this example, the inductor and CHF values were kept constant while varying LF.

II. High Frequency Capacitor (CHF) Selection
The high frequency capacitor (CHF) will set the inductor switching frequency of the D391A IC.
High inductor frequency allows for more efficient use of inductor coils with lower values.
However, care must be taken that the charge pumping does not reach a continuous mode at
very high frequency when the voltage is not efficiently transferred to the lamp load. Figure 3
graphically represents the effect of the CHF value on the oscillator frequency.

Figure 3—Typical inductor frequency vs. CHF capacitor
The inductor switching frequency may also be controlled with an external clock signal. The
inductor will charge during the low portion of the clock signal and discharge into the EL lamp
during the high portion of the clock signal. The positive duty cycle used for the external high
frequency clock signal is usually between 15%-75%, with a typical value of 15%-20% for maximum
brightness. The clock signal input voltage should not exceed V+.
III. Inductor (L) Selection
The inductor value and inductor switching frequency have the greatest impact on the output
brightness and current consumption of the EL driver. Figure 4 and Figure 5 on the following page
show the dependence of brightness and current draw of a D391A IC circuit on coil values and
CHF values for two sample EL lamp sizes and input voltages. The CHF value was chosen such
that the output voltage did not exceed 220Vpp. Note that the DC resistance (DCR) of inductors
with the same nominal inductance value may vary with manufacturer and inductor type.
Therefore, inductors made by a different manufacturer may yield different outputs, but the trend
of the different curves should be similar.

IV. D391A IC Operating Considerations
The following recommendations should be considered when designing and testing the D391A IC
device to ensure that the devices are not damaged.
1) An EL driver system using the D391A IC driver need to be designed with an output capacitor in
parallel with Vout pin to GND. Place the output capacitor close to the IC. The high voltage
capacitor should rate for minimum of 100V. This is use to reduce high frequency spikes caused
by high impedance seen at the Vout pin and prevent open load conditions.
2) The DC input supply voltage (V+) should be applied to the V+ pin of the D391A IC prior to the
application of the enable signal high to pin 3. Conversely, when powering off the device, the
enable signal must be low prior to the removal of V+ signal.
3) Prevent voltage spikes at V+. Place the V+ decoupling capacitor close to the IC. Avoid long
wires from the V+ power supply to the IC in the test environment.

D391A IC Design Ideas:
I. DC Bias Elimination Circuit
Semiconductor inverters will inherently induce a small DC bias across the electrodes of the EL
lamp. Elimination of DC bias in specific EL driving systems may improve performance and
prolong overall operation of the system. The Rogers patented (#7,009,346) DC bias elimination
circuit is a high pass filter connected between the Vout pin and EL lamp as shown below.

II. Driving Multiple EL Lamps
The D391A IC may be used to drive multiple EL lamp segments. An external transistor switching
circuit is used to turn each lamp segment on or off independently or simultaneously. A high
signal at the corresponding E input will enable the corresponding lamp segment. In this
configuration, EL Lamp 1 is always turned on when the IC is enabled. Otherwise, always make
sure that at least one lamp segment is selected to be on when the D391A IC is enabled.

The user should determine the suitability of Rogers’ EL systems for each application.
LIT-I9076 A02
Page 9 of 15
III. Two-level Dimming
Two level dimming may be achieved using the circuit configuration shown below. When DIM is
low, the external PNP transistor is saturated and the EL lamp runs at full brightness. When DIM is
high, the external PNP turns off and the 47Ω resistor reduces the voltage at (V+) and dims the EL
lamp.
IV. Lamp Frequency Control with an External Clock Signal
An external clock signal may be used to control the EL lamp frequency (LF) of the D391A IC
instead of using a capacitor. There is an internal frequency divider in the IC, however, so the
output lamp frequency will be one-sixteenth (6.25%) of the input clock signal. For example, if a
3.2kHz input clock signal is used, the resulting lamp frequency will be 200Hz. The clock signal
voltage should not exceed V+. A typical duty cycle for the clock input is +50%.

Page 10 of 15
V. EL Brightness Control through HF Clock Pulse Width Modulation
The inductor oscillating frequency may also be controlled on the D391A IC driver using an
external clock input to CHF. In addition, pulse-width modulation of the external HF clock signal
to the D391A IC may be used to regulate the brightness of the EL lamp load. High frequency
input is usually in the range of 25kHz to 100kHz, with duty cycle in the range of 15% to 75%. In
general, a lower duty cycle results in higher brightness. The clock signal voltage should not
exceed V+. Prior to finalization of the circuit, contact Rogers to verify that the frequency, duty
cycle, and setup chosen are acceptable for EL driver performance.
VI. Fade ON Fade OFF Output Control
When the EL lamp is changing from on to off a fading option can be implemented using
frequency control as an RC circuit on the CHF pin. The option of fading is separate from the
enabling of the EL drive utilizing the E pin logic. The added circuitry shown below can be
optimized to control the time interval of fading off (C1 and R1) as well as the interval of fading
on (C1 and R2). The application of D1 is optional with respect to the control system applied for
fading on and off. If the system does not have an internal diode other than D1, there may be
an undesired current flow from the inverter driver to the control system during a low signal.
