LT3517  
Full-Featured LED Driver  
with 1.5A Switch Current  
FEATURES  
DESCRIPTION  
5000:1 True Color PWMDimming 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 tradi-  
tional 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.  
1.5A, 45V Internal Switch  
100mV High Side Current Sense  
Open LED Protection  
Adjustable Frequency: 250kHz to 2.5MHz  
Wide Input Voltage Range:  
Operation from 3V to 30V  
Transient Protection to 40V  
Operates in Boost, Buck Mode and Buck-Boost Mode  
Gate Driver for PMOS LED Disconnect  
Constant-Current and Constant-Voltage Regulation  
CTRL Pin Provides 10:1 Analog Dimming  
Low Shutdown Current: <1μA  
Available in (4mm × 4mm) 16-Lead QFN and 16-Pin  
TSSOP Packages  
The LT3517 is available in the tiny footprint 16-lead QFN  
(4mm × 4mm) and the 16-pin TSSOP packages. The  
LT3517 provides a complete solution for both constant-  
voltage and constant-current applications.
