Step-Down 1A LED Driver

The LT3474 LT3474-1 are fixed frequency Step-down DC/DC converters designed to operate as constant-cur- rent sources. An internal sense resistor monitors the output current allowing accurate current regulation, ideal for driving high current LEDs High output current accu- racy is maintained over a wide current range, from 35mA to 1A, allowing a wide dimming range. Unique PWM circuitry allows a dimming range of 400:1, avoiding the color shift normally associated with LED current dimming. By Linear Technology Corporation
