The MAX14514 is a high-voltage DC-AC converter ideal
for driving two electroluminescent (EL) lamps. The
MAX14514 features a +2.7V to +5.5V input range that
allows the device to accept a wide variety of voltage
sources, including single-cell lithium-ion (Li+) batteries.
The lamp outputs of the device generate up to 300VP-P
for maximum lamp brightness.
The MAX14514 utilizes an inductor-based boost converter
to generate the high voltage necessary to drive EL
lamps and allows the use of a 220μH inductor to effectively
drive total combined lamp sizes of up to 20nF.
The MAX14514 uses a high-voltage full-bridge output
stage to convert the high voltage generated by the
boost converter to an AC waveform suitable for driving
the EL panels. An external resistor controls the slewrate
of the rising and falling edges of the AC drive
waveform to reduce audible noise output. The high-voltage
outputs are ESD protected up to ±15kV Human
Body Model, ±4kV IEC 61000-4-2 Air Gap Discharge,
and ±4kV IEC 61000-4-2 Contact Discharge.
