The MIC4832 is a low noise 220VPP electroluminescent (EL) lamp driver. Using advanced Bipolar, CMOS, DMOS (BCD) technology, the MIC4832 integrates a high voltage boost converter and an H-bridge driver for driving a large EL lamp. The MIC4832 can drive large panel displays for mobile phones, MP3 players, or automotive electronics where EL panels are used for backlighting. The MIC4832 offers design flexibility with adjustable lamp and boost converter frequencies, simply by applying external resistors. A new H-bridge design reduces audible noise by creating smoother AC voltage across the EL panel. The MIC4832 is offered in MSOP-8 lead-free and RoHS-compliant packaging with a -40°C to 85°C junction temperature range.
