Step-Down 1A LED DriverThe 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
