DESCRIPTION

FEATURES

The MP3802 is a high output voltage, DC to AC

•

2.5V to 5.5V DC Input Voltage

converter

designed

for

driving

240V_PPRegulated AC Output Waveform

Single Cell Lithium-Ion Compatible

10nA Shutdown Current

Adjustable EL Lamp Frequency

Adjustable Converter Frequency

Available in MSOP-8

Electroluminescent (EL) lamps of up to 5 square

inches. The device operates from an input

voltage range of 2.5V to 5.5V, making it suitable

for

1-cell

Li-Ion

and

3-cell

alkaline/NiCad/NiMH battery applications. The

device uses a single inductor and a minimum

number of passive components. The MP3802

converts a low-voltage DC input to a ±120V

regulated output voltage that drives the EL lamp.

Split Supply Capability

APPLICATIONS

•

Portable Multimedia Players

LCD Backlighting

PDAs

Handheld Wireless Communication

Mobile Phones

Remote Controls

The MP3802 is comprised of two stages: a boost

stage and a H-bridge lamp driver stage. The

boost stage converts the input voltage up to

120V. The H-bridge stage alternately switches

the 120V to each terminal of the EL lamp.

Global Positioning Systems (GPS)

The MP3802 has two separate internal

oscillators for the boost and H-bridge stages.

The frequency of each oscillator is set

independently via external resistors. This

flexibility allows the EL lamp circuit to be

optimized for maximum performance. Also, the

IC can be enabled /disabled by connecting these

two resistors to V_DD/GND.

“MPS” and “The Future of Analog IC Technology” are Registered Trademarks of

Monolithic Power Systems, Inc.

The MP3802 is available in an 8-pin MSOP

package.
