General Description  
The TS19371 is a step-up DC/DC converter specifically designed to drive white LEDs with a constant current. The  
device can drive up to 126 LEDs (9S14P) from a 12V supply. The output capacitor can be as small as 4.7µF,  
saving space versus alternative solutions. A low 95mV feedback voltage minimizes power loss for better  
efficiency. Additional feature include over output voltage limiting (SOT-26 package) when LEDs are disconnected.  
The TS19371 switches at a fixed frequency of 1.2MHz, allowing the use of tiny, low profile inductors and  
capacitors to minimize footprint and cost in space consideration applications for cellular phone backlighting or  
other hand held equipment.
