LM3406 Datasheet (National Semiconductor) - 1.5A Constant Current Buck Regulator

LM3406, 1.5A Constant Current Buck Regulator

The LM3406/06HV are monolithic switching regulators designed to deliver constant currents to high power LEDs.

Ideal for automotive, industrial, and general lighting applications, they contain a high-side N-channel MOSFET switch with a current limit of 2.0A (typical) for step-down (Buck) regulators.
