Low-Noise 220V_PPEL Driver

Features

General Description

• 1.8V to 5.5V DC Input Voltage

The

MIC4832

low-noise

220V_PP

electroluminescent lamp (EL) driver. Using advanced

Bipolar, CMOS, and DMOS (BCD) technology, the

MIC4832 integrates a high voltage boost converter and

an H-bridge driver for driving a large EL lamp.

• 220V_PPOutput Voltage Capable

• Low Audible Noise EL Drive Waveform

• Supports EL Panel Sizes up to 3 in²(19 cm²)

• Low 45 µA Operating Supply Current

• Small Inductor Size with Low Profile (220 µH)

• Tiny 8-Lead 3 mm x 3 mm DFN Package

• Adjustable Boost Converter Frequency

• Adjustable EL Lamp Frequency

The MIC4832 can drive large-panel displays for mobile

phones, multimedia players, or automotive electronics

where EL panels are used for backlighting.

The MIC4832 also 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.

• 10 nA Shutdown Current

Applications

• LCD Panel Backlight

• Mobile Phones

• PDAs

The MIC4832 is offered in a 3 mm x 3 mm DFN and

MSOP-8 lead-free and RoHS-compliant packaging

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

• Pagers

• Calculators

• Multimedia Players

• Remote Controls

• GPS Receivers
