VII. High EL Brightness Through Supply Voltage Doubling (Option 1)
Maximum brightness from a D355 is achieved at relatively high supply voltages (>3.0V). An external voltage boost
circuit may be used to increase the voltage supplied to the D355. In the following circuit, the National Semiconductor
LM2665 is used to double the voltage supplied to the D355. This can produce about twice the brightness of the D355
alone.
NOTE: It is important not to exceed the maximum ratings of either device in this circuit.

In many cases, a resistor may replace the diode in the previous circuit. The diode is used by the LM2665 during startup
(see LM2665 datasheet). The circuit below ensures that the LM2665 starts properly before the D355 is turned on.
