LM3410 Datasheet Constant Current Boost and SEPIC LED Driver

Manufacturer: National Semiconductor (now Texas Instruments)

General Description

The LM3410 constant current LED driver is a monolithic, high frequency, PWM DC/DC converter in 5-pin SOT23, 6-pin LLP, & 8-pin eMSOP 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.
