TC115  
PFM/PWM Step-up DC/DC Converter  
GENERAL DESCRIPTION  
FEATURES  
The TC115 is a high-efficiency step-up DC/DC con-  
verter for small, low input voltage or battery powered sys-  
tems. This device has a guaranteed 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 conven-  
tional PWM step-up converters, the TC115 automatically  
shifts to pulse frequency modulation (PFM) at low loads,  
resulting in reduced supply current and improved efficiency.  
The TC115 requires only an external diode, an inductor,  
and a capacitor, and supports typical output currents of 140  
mA.Supplycurrentisreducedtolessthan0.5µA,maxwhen  
SHDN input is brought low.  
High Efficiency at Low Output Load Currents  
via PFM Mode  
Space-Saving SOT-89 Package  
Start-Up at 0.9V  
80 µA (typ.) Supply Current  
85% (typ.) Efficiency at 100 mA  
140 mA Typical Output Current @ VIN = 2.0V  
Low Power Shutdown Mode  
No External Switching Transistor Needed  
TYPICAL APPLICATIONS  
Pagers  
Cellular Phones  
Palmtops  
1-Cell to 3-Cell Battery Powered Systems  
Cameras, Video Recorders  
Local +3V to +5V Supplies  
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.
