DataSheet.in LM3414/LM3414HV 1A 60W* Common Anode Capable Constant Current Buck LED Driver Requires No External Current Sensing Resistor August 9, 2010 LM3414/LM3414HV 1A 60W* Common Anode Capable Constant Current Buck LED Driver Requires No External Current Sensing Resistor General Description The LM3414 and LM3414HV are 1A 60W* common anode capable constant current buck LED drivers. They are exceptionally suitable to drive single string of 3W HBLED with up to 96% efficiency. They accept 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.
