description

®The LT 3519 / LT3519-1 / LT3519-2 is a fixed-frequency boost DC/DC converter designed specifically for driving LEDs. It features an internal 45V, 750mA low-end switch and Schottky diode. By combining a traditional voltage feedback with a unique rail-to-rail current sense feedback, the converter can act as a constant voltage source or a constant current source. Internal compensation simplifies application. The device features rail-to-rail LED current sense pins that provide maximum flexibility when selecting a converter configuration to drive the LEDs. The LED current can be set externally using a sense resistor. The external PWM provides up to 3000:1 PWM dimming, while the CTRL input provides analog dimming capabilities.
