LT3517  
Full-Featured LED Driver  
with 1.5A Switch Current  
Features  
Description  
The LT®3517 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 tradi-  
tional voltage loop and a unique current loop to operate  
as a constant-current source or constant-voltage source.
