Product Overview

The LM3414HVMREVAL/NOPB is a LM3414HV 65V LED driver PSOP8 evaluation board. This board is designed to drive up to 18 pieces of serial high brightness LEDs (HBLEDs) with up to 1000mA LED forward current. The LM3414HV is 1A 60W common anode capable constant current buck LED drivers. It is 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. With the incorporation of the proprietary pulse level modulation (PLM) technology, the LM3414HV requires no external current sensing resistor to facilitate LED current regulation. The LM3414HV features a dimming control input (DIM pin) that allows PWM dimming control.
  • Support LED power up to 60W

  • High contrast ratio
  • Integrated low side N channel MOSFET
  • 4.5V to 65V input voltage range
  • Constant switching frequency adjustable from 250KHz to 1000KHz
  • Support analog dimming and thermal fold back

Applications

Automotive, LED Lighting, Power Management

Warnings

This device has limited built in ESD protection. The leads should be shorted together or device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
