GENERAL DESCRIPTION

The LND1937 is a boost DC/DC LED Driver

with internal 36V internal switch packaged in a

space saving SOT23-5 package.

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.

device uses a low 95mV feedback voltage

maximizing efficiency & includes a shutdown

feature.

The LND1937 operates over a Tj=-40 to 125C

temperature range.
