LM3402 Datasheet (Texas Instruments) - 0.5-A Constant Current Buck Regulator

LM3402, 0.5-A Constant Current Buck Regulator

The LM3402/HV 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 Nchannel MOSFET switch with a current limit of 735 mA (typical) for step-down (Buck) regulators.
