description

LT^®The 3518 is a current-mode DC/DC converter with an internal 2.3A, 45V switch designed to drive LEDs. The LT3518 acts as an LED driver and operates in boost, buck and buck-boost modes. It combines a conventional voltage loop and a unique current loop to act as a constant current source or constant voltage source. Programmable switching frequency allows external components to be optimized for efficiency or component size requirements. Synchronizes the LT3518's switching frequency to an external clock signal. A 100mV sense resistor can be used to set the LED current externally. An external PWM input is provided3000:1 LED dimming capability. The CTRL pin is available additionally10:1Dimming ratio.

The LT3518 is available in a small footprint 16-lead QFN (4mm x 4mm) and 16-lead TSSOP packages. The LT3518 provides a complete solution for constant voltage and constant current applications.
