The MIC4830 is a low noise 180VPP electroluminescent (EL) lamp driver. Using advanced Bipolar, CMOS, DMOS (BCD) technology, the MIC4830 integrates a high voltage boost converter and an H-bridge driver for driving a large EL lamp. The MIC4830 can drive large panel displays for mobile phones, MP3 players, or automotive electronics where EL panels are used for backlighting. The MIC4830 offers design flexibility with adjustable lamp and boost converter frequencies, simply by applying external resistors.
