Linear Technology LT3517
The LT3517 operates as a LED driver in boost, buck mode and buck-boost mode. It combines a traditional voltage loop and a unique current loop to operate as a constant-current source or constant-voltage source. The switching frequency of LT3517 can be synchronized to an external clock signal.| Part No. | LT3517 |

DESCRIPTION
The LT®3517 is a current mode DC/DC converter with an internal 1.5A, 45V switch specifically designed to drive LEDs. Programmable switching frequency allows optimization of the external components for efficiency or component size. 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. The LT3517 is available in the tiny footprint 16-Lead QFN (4mm × 4mm) and the16-Pin TSSOP packages. The LT3517 provides a complete solution for both constant-voltage and constant-current applications. , LT, LTC and LTM are registered trademarks of Linear Technology Corporation.
