LT3474 - Step-Down 1A LED DriverThe LT®3474 isA fixed frequency step-down DC/DC converter designed to operate asA constant-current source. An internal sense resistor monitors the output current allowing accurate current regulation, ideal for driving high current LEDs. High output current accuracy is maintained overA wide current range, from 35mA to 1A, allowingA wide dimming range. Unique PWM circuitry allowsA dimming range of 400:1, avoiding the color shift normally associated with LED current dimming. The hig
