LM3404 Datasheet (Texas Instruments) - 1-A Constant Current Buck LED Driver

LM3404, 1-A Constant Current Buck LED Driver

The LM3404 and LM3404HV devices are monolithic switching regulators designed to deliver constant currents to high power LEDs.

Ideal for automotive, industrial, and general lighting applications, these devices contain a high-side N-channel MOSFET switch with a current limit of 1.5-A (typical) for ste
