LND1937

36V BOOST DC/DC LED DRIVER

GENERAL DESCRIPTION

FEATURES

The LND1937 is a boost DC/DC LED Driver

with internal 36V internal switch packaged in a

space saving SOT23-5 package.



High Efficiency

Low Cost

Drives up to 36V Vf of LEDs

Internal Bipolar Switch

2.5V to 10V Input

Up to 36V Output

1.2MHz Switching Frequency

Minimizes Inductor Sizes

The LND1937 is all that is required to boost

from supplies as low as 2.5V to a string of

LEDs with a combined forward voltage of as

much as 36V.

The LND1937 bipolar switch can handle up to

100mA, and switches at 1.2MHz allowing an

extremely small inductor to be used. The

device uses a low 95mV feedback voltage

maximizing efficiency & includes a shutdown

feature.

EFFICIENCY

The LND1937 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
