LM3410

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

Driver with Internal Compensation

General Description

Features

The LM3410 constant current LED driver is a monolithic, high

frequency, PWM step-up DC/DC converter in 5-pin SOT23,

6-pin LLP, & 8-pin eMSOP packages. With a minimum of ex-

ternal components the LM3410 is easy to use. It can drive

2.5A typical peak currents with an internal 160mΩ NMOS

switch. Switching frequency is internally set to either 525kHz

or 1.60MHz, allowing the use of extremely small surface

mount inductors and chip capacitors. Even though the oper-

ating frequency is high, efficiencies up to 88% are easy to

achieve. External shutdown is included, featuring an ultra-low

stand-by current of 80nA. The LM3410 utilizes current-mode

control and internal compensation to provide high-perfor-

mance over a wide range of operating conditions. Additional

features include dimming, pulse-by-pulse current limit, and

thermal shutdown.
