The LM3405 is a step-down regulator with an output voltage range extending from a V O(MIN) of 205mV (the reference voltage) to a V O(MAX) determined by the maximum duty cycle (typically 94%). It can drive up to 3 LEDs in series at 1A forward current, with the single LED forward voltage of approximately 3.7V (Typical of white, blue, and green ...

The LM3405 is a PWM, current-mode control switching buck regulator designed to provide a simple, high efficiency solu-tion for driving LEDs with a preset switching frequency of 1.6MHz. This high frequency allows the LM3405 to operate with small surface mount capacitors and inductors, resulting in LED drivers that need only a minimum amount of board
