MIC4826

Low Input Voltage, 160 V_PPOutput Voltage, EL Driver

Features

General Description

• 1.8V to 5.5V DC Input Voltage

The MIC4826 is a high output voltage, DC to AC

converter, designed for driving Electroluminescent (EL)

lamps. The device operates from an input voltage

range of 1.8V to 5.5V, making it suitable for 1-cell Li Ion

and 2- or 3-cell alkaline, NiCad, and NiMH battery

applications. The MIC4826 converts a low voltage DC

input to a 160 V_PPAC output signal that drives the EL

lamp.

• 160 V_PPRegulated AC Output Waveform

• Independently Adjustable EL Lamp Frequency

• Independently Adjustable Boost Converter

Frequency

• 0.1 µA Shutdown Current

Applications

• LCD Panel Backlight

• Cellular Phones

• PDAs

The MIC4826 has two stages: a boost stage, and an

H-bridge lamp driver stage. The boost stage steps the

input voltage up to +80V. The H-bridge stage then

alternately switches the +80V output to each terminal

of the EL lamp, thus creating a 160 V_PPAC signal to

drive the EL lamp and generate light.

• Pagers

• Calculators

• Remote Controls

• Portable Phones

The MIC4826 features separate oscillators for the

boost and H-bridge stages. External resistors

independently set the operating frequency of each

stage. This flexibility allows the EL lamp circuit to be

optimized for maximum efficiency and brightness.

The MIC4826 uses a single inductor and a minimum

number of external components, making it ideal for

portable, space-sensitive applications.

The MIC4826 is available in an 8-lead MSOP package

with an ambient temperature range of –40°C to +85°C.
