General Description
The MAX14521E is a quad-output high-voltage DC-AC converter that drives four
electroluminescent (EL) lamps. The device features a 2.7V to 5.5V input range
that allows the device to accept a variety of voltage sources such as single-
cell lithium-ion (Li+) batteries. The lamp outputs of the device generate up
to 300VP-P for maximum lamp brightness. The high-voltage outputs are ESD
protected up to ±15kV Human Body Model (HBM), ±6kV Contact Discharge, and ±8kV
Air Gap Discharge, as specified in IEC 61000-4-2.
The MAX14521E uses a high-voltage full-bridge output stage to convert the high
voltage generated by the boost converter to a sinusoidal output waveform. The
MAX14521E utilizes a high-frequency spread-spectrum oscillator to reduce the
amount of EMI/EFI generated by the boost-converter circuit.
The MAX14521E provides an I2C interface to set the boost converter and EL
output switching frequencies through an 8-bit register and the peak output
voltages with 5 bits of resolution. The MAX14521E also provides an adjustable
automatic ramping feature that slowly increases or decreases the peak output
voltage when a change is made to the output amplitude. The slew rate of the
automatic ramp is set with 3 bits of resolution through the I2C interface and
it is independent for each channel. The MAX14521E features an audio auxiliary
input AUX that modulates the EL output voltage and frequency for dynamic
lighting effects.
The MAX14521E is available in a small, 4mm x 4mm, 24-pin TQFN package, and
specified over the extended -40°C to +85°C operating temperature range.
