FEATURES  
DESCRIPTION  
•
90% Efficient Synchronous Boost Converter  
–
–
75-mA Output Current at 3.3 V From 0.9-V  
Input  
The TPS6107x devices provide a power supply  
solution for products powered by either a one-cell,  
two-cell, or three-cell alkaline, NiCd or NiMH, or  
one-cell Li-ion or Li-polymer battery. Output currents  
can go as high as 75 mA while using a single-cell  
alkaline, and discharge it down to 0.9 V. It can also  
be used for generating 5 V at 200 mA from a 3.3 V  
rail or a Li-ion battery. The boost converter is based  
on a fixed frequency, pulse-width-modulation (PWM)  
controller using a synchronous rectifier to obtain  
maximum efficiency. At low load currents the  
TPS61070 and TPS61073 enter the power-save  
mode to maintain a high efficiency over a wide load  
current range. The power-save mode is disabled in  
the TPS61071 and TPS61072, forcing the converters  
to operate at a fixed switching frequency. The  
maximum peak current in the boost switch is typically  
limited to a value of 600 mA.  
150-mA Output Current at 3.3 V From 1.8-V

Load Disconnect During Shutdown  
Overtemperature Protection  
Small 6-Pin Thin SOT23 Package  
APPLICATIONS  
•
All One-Cell, Two-Cell, and Three-Cell Alkaline,  
NiCd or NiMH or Single-Cell Li  
Battery-Powered Products  
Portable Audio Players  
PDAs  
Cellular Phones  
The TPS6107x output voltage is programmed by an  
external resistor divider. The converter can be  
disabled to minimize battery drain. During shutdown,  
the load is completely disconnected from the battery.  
The device is packaged in a 6-pin thin SOT23  
package (DDC).
