FEATURES  
DESCRIPTION  
The LT®3593 is a step-up DC/DC converter designed to  
drive up to ten white LEDs in series from a Li-Ion cell.  
Series connection of the LEDs provides identical LED  
currents and eliminates the need for ballast resistors. The  
device features a unique high side LED current sense that  
enables the part to function as a “one wire current source”  
where the low side of the LED string can be returned to  
ground anywhere.

APPLICATIONS  
The LT3593 switches at 1MHz, allowing the use of tiny  
external components. Constant frequency switching re-  
sults in low input noise and a small output capacitor. The  
LT3593 is available in the 6-lead DFN (2mm × 2mm) as  
well as the 6-lead SOT-23 packages.
