Integrated OLED Display Power Supply and  
LED Driver  
Dual Display LCD Backlighting for Portable  
Applications  
Drives up to 10 LED’s at 30mA  
Large Format LCD Backlighting  
OLED Panel Power Supply  
Drives up to 5 LED’s at 20mA and Delivers up  
to 21V at 40mA  
DESCRIPTION  
Over 90% Efficient  
The LM3509 current mode boost converter offers two  
separate outputs. The first output (MAIN) is a  
constant current sink for driving series white LED’s.  
The second output (SUB/FB) is configurable as a  
constant current sink for series white LED bias, or as  
a feedback pin to set a constant output voltage for  
powering OLED panels.  
32 Exponential Dimming Steps  
0.15% Accurate Current Matching Between  
Strings  
Internal Soft-Start Limits Inrush Current  
True Shutdown Isolation for LED’s  
Wide 2.7V to 5.5V Input Voltage Range  
21V Over-Voltage Protection  
1.27MHz Fixed Frequency Operation  
Low Profile 10-Pin WSON Package (3mm x  
3mm x 0.8mm)
