Product Summary

The LM3401MMX/NOPB is a switching controller designed to provide constant current to high power LEDs. The LM3401 drives an external P-MOSFET switch for step-down (Buck) regulators. The LM3401MMX/NOPB delivers constant current within ±6% accuracy to a wide variety and number of series connected LEDs. Output current is adjusted with an external current sensing resistor to drive high power LEDs in excess of 1A. The applications of the LM3401MMX/NOPB include LED Driver and Battery Charger.
