90% EFFICIENT SYNCHRONOUS BOOST CONVERTER WITH 600-mA SWITCH  
FEATURES  
DESCRIPTION  
•
90% Efficient Synchronous Boost Converter  
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 enters the power-save mode to maintain a  
high efficiency over a wide load current range. At the  
TPS61071 the power-save mode is disabled, forcing  
the converter to operate at a fixed switching fre-  
quency. The maximum peak current in the boost  
switch is typically limited to a value of 600 mA.  
– 75-mA Output Current at 3.3 V From 0.9-V

– 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  
The TPS6107x output voltage is programmed by an  
external resistor divider. The converter can be dis-  
abled 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).
