Description

  • LM3405A-REF, LM3405A Reference Design for the LED driver has been used for this design. It is a current mode control buck switching regulator designed to provide a simple, high efficiency solution for driving high power LEDs (Typical Vf = 3.8V). 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. The LM3405A uses internal compensation offering ease of use and predictable, high performance regulation over a wide range of operating conditions. Additional features include user accessible EN/DIM pin for enabling and PWM dimming of LEDs, thermal shut-down, cycle-by-cycle current limit and over-current protection
