Product Overview
LT3519-1 is a fixed frequency step-up DC/DC converter designed to drive LEDs. It feature an internal 45V, 750mA low side switch and Schottky diode. Combining a traditional voltage feedback and a 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 feature 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. It is widely used in application such as automotive, industrial, constant current source, current limited constant voltage source etc.
- VIN operating voltage range is 3V to 30V
- VIN supply current is 0.1μA typical
- Rail-to-rail LED current sense from 0V to 45V
- Switch current limit is 980mA typical
- Switch VCESAT is 300mV typical
- Internal schottky diode, constant-current and constant-voltage regulation
- Open LED protection and open LED status pin, programmable undervoltage lockout with hysteresis
- Internal compensation, CTRL pin provides analogue dimming
- Operating temperature is -40°C to 125°C
- Package style is 16-lead plastic MSOP
