Product Summary

The LM3414HVMRX is a 1A 60W common anode capable constant current buck LED driver. The device is exceptionally suitable to drive single string of 3W HBLED with up to 96% efficiency. The LM3414HVMRX accepts input voltages from 4.5VDC to 65VDC and deliver up to 1A average LED current with ±3% accuracy. The integrated low-side N-channel power MOSFET and current sensing element realize simple and low component count circuitry as no bootstrapping capacitor and external current sensing resistor are required. An external smallsignal resistor to ground provides very fine LED current adjustment, analog dimming as well as thermal fold-back functions. The applications of the LM3414HVMRX include High Power LED Driver, Architectural Lighting, Office Troffer, Automotive Lighting and MR-16 LED Lamp.
