96% Efficient Synchronous Boost Converter  
The TPS6102x 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 200 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 500 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  
converter enters the Power Save mode to maintain a  
high efficiency over a wide load current range. The  
Power Save mode can be disabled, forcing the  
converter to operate at a fixed switching frequency.  
The maximum peak current in the boost switch is  
limited to a value of 800 mA, 1500 mA or 1800mA  
depending on the device version.

Over-Temperature Protection  
Small 3 mm × 3 mm QFN-10 Package  
The TPS6102x devices keep the output voltage  
regulated even when the input voltage exceeds the  
nominal output voltage. The output voltage can be  
programmed by an external resistor divider, or is  
fixed internally on the chip. The converter can be  
disabled to minimize battery drain. During shutdown,  
the load is completely disconnected from the battery.  
A low-EMI mode is implemented to reduce ringing  
and, in effect, lower radiated electromagnetic energy  
when the converter enters the discontinuous  
conduction mode. The device is packaged in a 10-pin  
QFN PowerPAD™ package measuring 3 mm x 3 mm  
(DRC).
