MIC4830

Low Noise 180Vp-p EL Driver

General Description

Features

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.

• 1.8V to 5.5V input voltage

• 180Vpp output voltage

• Low audible noise EL drive waveform

• Supports EL panel sizes up to 4in²(25cm²)

• Low 45µA operating supply current

• Small inductor size with low profile (220µH)

• Tiny 3mm × 3mm MLF^®-8L package

• Adjustable boost converter frequency

• Adjustable EL lamp frequency

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.

• Low 10nA shutdown current

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.
