LM3405A Datasheet (Texas Instruments) - 1.6-MHz 1-A Constant Current Buck LED Driver

LM3405A, 1.6-MHz 1-A Constant Current Buck LED Driver

The LM3405A is a 1-A constant current buck LED driver designed to provide a simple, high efficiency solution for driving high power LEDs.

With a 0.205-V reference voltage feedback control to minimize power dissipation, an external resistor sets the current as needed for driving various types of LEDs
