FeaTures  
DescripTion  
The LT®3513 5-output adjustable switching regulator  
provides power for large TFT-LCD panels. The 38-pin  
5mm × 7mm QFN device can generate a 3.3V or 5V logic  
supply along with the triple output supply required for the  
TFT-LCD panel. A lower voltage secondary logic supply  
may also be generated with the addition of an external  
NPN driven by the internal linear regulator. A step-down
