SNVS541G –OCTOBER 2007–REVISED MAY 2013

525kHz/1.6MHz, Constant Current Boost and SEPIC LED Driver with Internal

Compensation

Check for Samples: LM3410, LM3410Q

FEATURES

DESCRIPTION

The LM3410 constant current LED driver is a

monolithic, high frequency, PWM DC/DC converter in

5-pin

•

Space Saving SOT-23 and WSON Packages

Input Voltage Range of 2.7V to 5.5V

Output Voltage Range of 3V to 24V

2.8A Typical Switch Current

•

SOT-23, 6-pin WSON, and 8-pin MSOP-PowerPad™

packages. With a minimum of external components

the LM3410 is easy to use. It can drive 2.8A typical

peak currents with an internal 170 mΩ NMOS switch.

Switching frequency is internally set to either 525 kHz

or 1.60 MHz, allowing the use of extremely small

surface mount inductors and chip capacitors. Even

though the operating frequency is high, efficiencies

up to 88% are easy to achieve. External shutdown is

included, featuring an ultra-low standby current of 80

nA. The LM3410 utilizes current-mode control and

internal compensation to provide high-performance

over a wide range of operating conditions. Additional

features include dimming, cycle-by-cycle current limit,

and thermal shutdown.

High Switching Frequency
