Product Overview

The LT3517IFE#PBF is a current mode DC/DC Converter with an internal 1.5A, 45V switch specifically designed to drive LEDs. The LT3517 operates as a LED driver in boost, buck mode and buck-boost mode. It combines a traditional voltage loop and unique current loop to operate as a constant-current source or constant-voltage source. Programmable switching frequency allows optimization of the external components for efficiency or component size. The switching frequency of LT3517 can be synchronized to an external clock signal. The LED current is externally programmable with a 100mV sense resistor. The external PWM input provides up to 5000:1 LED dimming. The CTRL pin provides further 10:1 dimming ratio.
  • Open LED protection
  • Gate driver for PMOS LED disconnect
  • Constant-current and constant-voltage regulation
  • <1µA Low shutdown current
  • 100mV High-side current sense
