MIC4832 Overview
The MIC4832 is a low-noise 220VPP electroluminescent lamp (EL) driver. Using advanced Bipolar, CMOS, and 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, multimedia players, or automotive electronics where EL panels are used for backlighting.
