Product Overview


The LM3405AEVAL evaluation board is configured to drive a series string of high power, high brightness LEDs at a forward current of 1A using the LM3405A constant current buck regulator. The converter output voltage adjusts as needed to maintain a constant current through the LED array. The LM3405A is a step down regulator with an output voltage range extending from a VO(MIN) of 205mV (the reference voltage) to a VO(MAX) determined by the maximum duty cycle (typically 94%). It can drive up to five LEDs in series at 1A forward current, with the single LED forward voltage of approximately 3.7V (Typical of white, blue and green LEDs using InGaN technology).
  • input voltage range of 3V to 22V
  • Drives up to five high brightness LEDs in series at 1A
  • 1.6MHz switching frequency
  • EN/DIM input for enabling and PWM dimming of LEDs
  • 300mΩ NMOS switch
  • 40nA shutdown current at VIN = 5V
  • Internally compensated current mode control
  • Cycle by cycle current limit
  • Input voltage UVLO
  • Over current protection
