LM3414HV - 60-W Common Anode-Capable Constant Current Buck LED Driver

Download the LM3414HV datasheet PDF. This datasheet also covers the LM3414 variant, as both devices belong to the same 60-w common anode-capable constant current buck led driver family and are provided as variant models within a single manufacturer datasheet.

General Description

The LM3414 and LM3414HV are 1-A 60-W(1) common anode-capable constant current buck LED drivers.

They are suitable for driving single string of 3W HBLED with up to 96% efficiency.

They accept input voltages from 4.5 VDC to 65 VDC and deliver up to 1-A average LED current with ±3% accuracy.

Key Features

  • 1 Supports LED Power up to 60 W (1): 18x 3-W HBLEDs.
  • Requires No External Current Sensing Resistor.
  • ±3% LED Current Accuracy.
  • Up to 96% Efficiency.
  • High Contrast Ratio (Minimum Dimming Current Pulse Width.
