400-mA, 1.25-MHz, HIGH-EFFICIENCY, STEP-DOWN CONVERTER IN THIN-SOT23  
FEATURES  
DESCRIPTION  
•
High-Efficiency Synchronous Step-Down Con-  
verter 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 6.0-V Input Voltage Range  
Adjustable Output Voltage Range From 0.7 V  
to VI  
With an output voltage range of 6.0 V down to 0.7 V  
and up to 400-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 1.25 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.
