MIC4830
Low Noise 180V
PP
EL Driver
General Description
The MIC4830 is a low noise 180V
PP
electroluminescent
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 phones, multimedia players or automotive
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
®
3mm × 3mm and
MSOP-8 Pb-free and RoHS-compliant packaging with a
–40°C to 85°C junction temperature range.
Datasheets and support documentation can be found on
Micrel’s web site at: www.micrel.com.
