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.
