The MAX14521E from Maxim is a quad-output high-voltage DC-AC converter that drives four electroluminescent (EL) lamps. The device features a 2,7 V to 5,5 V input range that allows it to accept a variety of voltage sources such as single-cell lithium-ion (Li+) batteries. The lamp outputs of the device generate up to 300 VP-P for maximum lamp brightness. The high-voltage outputs are ESD protected up to ±15 kV human body model (HBM), ±6 kV contact discharge and ±8 kV air gap discharge, as specified in IEC 61000-4-2.
The IC uses a high-voltage full-bridge output stage to convert the high voltage generated by the boost converter to a sinusoidal output waveform. It utilises a high-frequency spread-spectrum oscillator to reduce the amount of EMI/EFI generated by the boost-converter circuit. The device 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 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 IC features an audio auxiliary input AUX that modulates the EL output voltage and frequency for dynamic lighting effects. It is available in a 4 x 4 mm, 24-pin TQFN package, and specified over the extended -40°C to +85°C operating temperature range.
