40V, 1.3A, Single-cell Step-up

White LED Driver

with Single Wire Dimming Control

The Future of Analog IC Technology

DESCRIPTION

FEATURES

The MP3302 is a step-up converter designed for

driving arrays of WLEDS from a single cell

Lithium Ion battery. The MP3302 uses current

mode, fixed frequency architecture to regulate the

LED current, which is measured through an

external current sense resistor. Its low 200mV

feedback voltage reduces power loss and

improves efficiency. The MP3302 is turned off if

an over-voltage condition is present due to an

open circuit condition.

•

Internal Power MOSFET

Drives up to 10 Series White LEDs

Up to 87% Efficiency

Single Wire Dimming Control

1.3MHz Fixed Switching Frequency

Open Load Shutdown

Low 200mV Feedback Voltage

UVLO, Thermal Shutdown

Internal 1.3A Current Limit

Available in TSOT23-5 and 2mm x 3mm

QFN8 Packages

The MP3302 includes under-voltage lockout,

current limiting and thermal overload protection

preventing damage in the event of an output

overload.

APPLICATIONS

•

5” ~ 7” LCD Panels

Handheld Computers and PDAs

Digital Still Cameras

The MP3302 is available in small 5-pin TSOT23

and 8-pin QFN (2mm x 3mm) packages.
