General Description  
Applications  
The TC115 is a high-efficiency step-up DC/DC  
converter for small, low input voltage or battery-  
powered systems. This device has a start-up voltage  
of 0.9V and a typical supply current of 80 µA. Phase  
compensation and soft-start circuitry are included on-  
chip. Unlike conventional PWM step-up converters,  
the TC115 automatically shifts to pulse frequency  
modulation (PFM) at low loads, resulting in reduced  
supply current and improved efficiency.  
• Pagers  
• Cellular Phones  
• Palmtops  
• 1-Cell to 3-Cell Battery Powered Systems  
• Cameras, Video Recorders  
• Local +3V to +5V Supplies  
The TC115 requires only an external diode, an inductor  
and a capacitor, while supporting typical output cur-  
rents of 140 mA. Supply current is reduced to less than  
0.5 µA (max) when SHDN input is brought low.  
Small size, low installed cost and low supply current  
make the TC115 step-up converter ideal for use in a  
wide range of battery-powered systems.
