LND3465

30V BOOST DC/DC LED DRIVER

GENERAL DESCRIPTION

FEATURES

The LND3465 is a boost DC/DC LED Driver

with internal 30V internal switch packaged in a

space saving SOT23-6 package.



High Efficiency

Low Cost

2.7 to 16V Vin

Drives up to 30V Vf of LEDs

No External Schottky Required

Internal Switch

Built in Soft Start

Open LED Protection

Up to 30V Output

Dimming CTRL Pin for Wide Contrast

Ratio Dimming

1.2MHz Switching Frequency

Minimizes Inductor Size

Small SOT23-6 Package

The LND3465 is all that is required to boost

from supplies as low as 2.7V to a string of

LEDs with a combined forward voltage of as

much as 30V.

The LND3465 can drive a switch current

current up to 200mA, and switches at 1.2MHz

allowing an extremely small inductor to be

used. The device uses a low 200mV feedback



voltage maximizing efficiency.

No external

schottky diode is required reducing component

count.

EFFICIENCY

The LND3465 includes

dimming input that may be used for wide

contrast dimming applications. Additional

shutdown and

features include open LED protection and

output voltage limiting if LEDs become

disconnected.

The LND3465 operates over a Tj=-40 to 125C

temperature range.

TYPICAL APPLICATION

APPLICATIONS



Cellular Phone Backlights

PDAs, Handheld Computers

Digital Cameras

MP3 Players

GPS Receivers
