description

LT^®The 3519/LT3519-1/LT3519-2 are fixed frequency step-up DC/DC converters designed to drive LEDs. It features an internal 45V, 750mA low-side switch and Schottky diode. The combination of a traditional voltage feedback and a unique rail-to-rail current sense feedback allows the converter to function as a constant voltage source or constant current source. Internal compensation simplifies the application. The device has rail-to-rail LED current-sense pins that provide maximum flexibility in selecting a converter configuration to drive the LEDs. The LED current can be set externally with a sense resistor. The external PWM provides PWM dimming up to 3000:1, while the CTRL input provides analog dimming.
