Applications  
General Description  
• Pagers  
The TC115 is  
a high-efficiency step-up DC/DC  
• Cellular Phones  
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 80µA. 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.  
• Palmtops  
• 1-Cell to 3-Cell Battery Powered Systems  
• Cameras, Video Recorders  
• Local +3V to +5V Supplies  
Device Selection Table  
The TC115 requires only an external diode, an  
inductor, and a capacitor, and supports typical output  
currents of 140mA. Supply current is reduced to less  
than 0.5µA, 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.
