1 / 12 page MIC4830 Low Noise 180Vp-p EL Driver MLF and MicroLead Frame are registered trademark of Amkor Technologies Micrel Inc. • 2180 Fortune Drive • San Jose, CA 95131 • USA • tel +1 ( 408) 944-0800 • fax + 1 (408) 474-1000 • http://www.micrel.com September 2007 M9999-091307 (408) 955-1690 General Description The MIC4830 is a low noise 180Vp-p 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. Data sheets and support documentation can be found on Micrel’s web site at www.micrel.com.
