Product Overview

The LM3405AXMK/NOPB is a 1A constant current buck LED Driver designed to provide a simple and high efficiency solution for driving high power LEDs. With a 0.205V reference voltage feedback control to minimize power dissipation, an external resistor sets the current as needed for driving various types of LEDs. Switching frequency is internally set to 1.6MHz, allowing small surface mount inductors and capacitors to be used. The LM3405A utilizes current-mode control and internal compensation offering ease of use and predictable, high performance regulation over a wide range of operating conditions. With a maximum input voltage of 22V, it can drive up to 5 high-brightness LEDs in series at 1A forward current, with the single LED forward voltage of approximately 3.7V. Additional features include user accessible EN/DIM pin for enabling and PWM dimming of LEDs, thermal shutdown, cycle-by-cycle current limit and overcurrent protection.
  • EN/DIM input for enabling and PWM dimming of LEDs
  • Internally compensated current-mode control

  • Input voltage UVLO
  • Overcurrent protection
  • Thermal shutdown
  • 300mΩ NMOS switch
  • 40nA Shutdown current at VIN=5V
  • Green product and no Sb/Br
