MAX14521E DC-AC converter

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.
Main features of the MAX14521E are : 300VP-P Maximum Output for Highest Brightness , ESD-Protected EL Lamp Outputs , ±15kV Human Body Model , ±6kV IEC 61000-4-2 Contact ESD Protection , ±8kV IEC 61000-4-2 Air Gap Discharge , 2.7V to 5.5V Input Voltage Range , I²C Interface ( for Control of Brightness, EL Frequency, Boost Frequency, Shape ) , Sinusoidal Output for Low Audible Noise , Individual Dimming Control , Individually Adjustable Output Brightness Ramping Rate , ±3% EL Output Frequency Accuracy for Truest EL Panel Color , Audio Input for Dynamic Lighting Effects , Spread-Spectrum Boost Converter , 100nA Shutdown Current .
