Maxim IC introduces the MAX14521E quad-output high-voltage DC-AC converter that drives four electroluminescent (EL) lamps. The input voltage range of the max14521 is between 2.7V to 5.5V 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.
