FEATURES  
DESCRIPTION  
•
High Efficiency Synchronous Step-Down  
The TPS6220x devices are a family of high-efficiency  
synchronous step-down converters ideally suited for  
portable systems powered by 1-cell Li-Ion or 3-cell  
NiMH/NiCd batteries. The devices are also suitable  
to operate from a standard 3.3-V or 5-V voltage rail.  
Converter With up to 95% Efficiency  
•
•
2.5-V to 6-V Input Voltage Range  
Adjustable Output Voltage Range From 0.7 V  
to VI  
•
•

•
Fixed Output Voltage Options Available  
Up to 300 mA Output Current  
With an output voltage range of 6 V down to 0.7 V  
and up to 300 mA output current, the devices are  
ideal to power low voltage DSPs and processors  
used in PDAs, pocket PCs, and smart phones.  
Under nominal load current, the devices operate with  
a fixed switching frequency of typically 1 MHz. At  
light load currents, the part enters the power save  
mode operation; the switching frequency is reduced  
and the quiescent current is typically only 15 µA;  
therefore, it achieves the highest efficiency over the  
entire load current range. The TPS6220x needs only  
three small external components. Together with the  
SOT23 package, a minimum system solution size is  
achieved. An advanced fast response voltage mode  
control scheme achieves superior line and load  
regulation with small ceramic input and output  
capacitors.
