MIC4834

Low Noise Dual 220 V_PPEL Driver

General Description

Features

•

Drives two EL panels, up to 3 in²each at full

brightness

The MIC4834 is a low noise dual Electroluminescent (EL)

Panel driver used in backlighting applications. The

MIC4834 converts a low DC voltage to a high DC voltage

using a boost converter and then alternates the high DC

voltage across the EL panels using an H-bridge. The

MIC4834 incorporates internal wave-shaping circuitry

specifically designed to reduce audible noise emitted by

EL panels. With only one inductor the MIC4834 can drive

two outputs and requires a minimum number of passive

components. It features an operating input voltage range

of 2.3V to 5.8V, making it suitable for 1-cell Li-ion and 2- or

3-cell alkaline/NiCad/NiMH battery applications.

220V_PPregulated AC output waveform

2.3V to 5.8V DC input voltage

Wave-shaping circuit to reduce audible noise

Adjustable boost converter frequency

Single inductor to power both panels

0.1µA typical shutdown current

Package options

−

10-pin 3mmx3mm MLF^®

10-pin MSOP

•

–40^oC to +125^oC junction temperature range

The MIC4834 features separate oscillators for the boost

and H-bridge stages. The boost frequency may be

adjusted with an external resistor to optimize efficiency

and brightness. The H-bridge frequency is internally preset

to 225Hz, to reduce the number of external components

and layout space.

Applications

•

Mobile phones

MP3/portable media players (PMP)

Clocks/ watches

Remote controls

Cordless phones

GPS devices

The MIC4834 is available in 10 pin 3mmx3mm MLF^®

package as well as MSOP-10L, and has an operating

junction temperature range of –40°C to +125°C.
