LT3517  
Full-Featured LED Driver  
with 1.5A Switch Current  
FEATURES  
DESCRIPTION  
5000:1 True Color PWM™ Dimming Ratio  
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 traditional  
voltage loop and a unique current loop to operate as  
a constant-current source or constant-voltage source.  
Programmableswitchingfrequencyallowsoptimizationof  
theexternalcomponentsforefficiencyorcomponentsize.  
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  
PWMinputprovidesupto5000:1LEDdimming.TheCTRL  
pin provides further 10:1 dimming ratio.
