FEATURES  
DESCRIPTION  
•
High-Efficiency Synchronous Step-Down  
Converter With up to 95% Efficiency  
The TPS6222x 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.  
•
•
2.5-V to 6-V Input Voltage Range  
Adjustable Output Voltage Range From 0.7 V  
to VI  
With an output voltage range of 6 V down to 0.7 V  
and up to 400-mA output current, the devices are  
ideal for powering the low voltage TMS320™ DSP  
family and processors used in PDAs, pocket PCs,  
and smart phones. Under nominal load current, the  
devices operate with a fixed switching frequency of  
typically 1.25 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, the device achieves  
the highest efficiency over the entire load current  
range. The TPS6222x needs only three small  
external components. Together with the tiny TSOT23  
package, a minimum system solution size can be  
achieved. An advanced fast response voltage mode  
control scheme achieves superior line and load  
regulation with small ceramic input and output  
capacitors.
