Product Overview

The LT3519EMS#PBF is a fixed frequency step-up DC/DC Converter designed to drive LEDs. It features an internal 45V, 750mA low-side switch and Schottky diode. Combining a traditional voltage feedback and unique rail-to-rail current sense feedback allows this converter to operate as a constant-voltage source or constant-current source. Internal compensation simplifies applications. This device features rail-to-rail LED current sense pins that provide the most flexibility in choosing a converter configuration to drive the LEDs. The LED current is externally programmable with a sense resistor. The external PWM provides up to 3000:1 PWM dimming and the CTRL input provides analogue dimming.
  • Constant-current and constant-voltage regulation
  • Open LED protection and open LED status pin
  • Programmable under-voltage lockout with hysteresis
  • Internal compensation
  • CTRL pin provides analogue dimming
  • Internal Schottky diode
  • <1µA Low shutdown current
