MIC4832

Low Noise 220V_PPEL Driver

General Description

Features

The MIC4832 is a low noise 220V_PPelectroluminescent

lamp (EL) driver. Using advanced Bipolar, CMOS, 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.

• 1.8V to 5.5V DC input voltage

• 220Vpp output voltage capable

• Low audible noise EL drive waveform

• Supports EL panel sizes up to 3in²(19cm²)

• Low 45µA operating supply current

• Small inductor size with low profile (220uH)

• Tiny 8-pin 3mm x 3mm MLF^®package

• Adjustable boost converter frequency

• Adjustable EL lamp frequency

The MIC4832 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.

• 10nA shutdown current

The MIC4832 is offered in MLF^®3mm x 3mm and MSOP-

8 lead-free and RoHS-compliant packaging with a -40°C to

85°C junction temperature range.
