GENERAL DESCRIPTION
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. A new H-Bridge design reduces audible noise by creating smoother AC voltage across the EL panel. The MIC4832 is offered in MLF® 3mm x 3mm and MSOP8 lead-free and RoHS-compliant packaging with a -40°C to 85°C junction temperature range.
