General Description

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.

The MIC4832 also 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 a 3 mm x 3 mm DFN and

MSOP-8 lead-free and RoHS-compliant packaging

with a –40°C to 85°C junction temperature range.
