Resumen del producto

The LM3405AXMYEVAL is a LM3405A 1.6MHz, 1A constant current buck LED driver with eMSOP package evaluation module. With a 0.205V reference voltage feedback control to minimise 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.
  • 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
