Description
The LT3475EFE-1#PBF is a dual step-down DC/DC converter designed to operate as a constant-current source specifically designed for LED drivers. It features an internal sense resistor that monitors the output current, allowing accurate current regulation that is ideal for driving high current LEDs. The high side current sense allows grounded cathode LED operation. High output current accuracy is maintained over a wide range, from 50mA to 1.5A, allowing a wide dimming range. The unique PWM circuitry allows a dimming range of 3000:1, avoiding the color shift normally associated with LED current dimming.
