LM3404HVMRX/NOPB is a 75 V constant-current buck LED driver with an integrated 1 A MOSFET, intended for high-power LED strings and PWM dimming.

Best for

  • High-voltage LED strings
  • Constant-current buck LED drivers
  • PWM-dimmed lighting

Avoid if

  • Input voltage can exceed 75 V
  • A synchronous converter is required
  • The LED load cannot maintain continuous inductor current

Check before use

  • Verify maximum LED-string voltage against duty-cycle and minimum off-time limits.
  • Select an inductor that does not saturate above the current-limit condition.
  • Place the bootstrap and input capacitors close to the IC pins.
