General Description

The MIC4830 is a low noise 180V

lamp (EL) 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

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. A new H-Bridge design reduces audible

noise by creating smoother AC voltage across the EL

panel.

The MIC4830 is offered in MLF

MSOP-8 Pb-free and RoHS-compliant packaging with a

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