com 19-4466; Rev 0; 2/09 KIT ATION EVALU E L B A IL AVA Dual Electroluminescent Lamp Driver General Description 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.
