FEATURES  
DESCRIPTION  
High Efficiency Step Down Converter  
Output Current up to 1000 mA  
The TPS6229x device is  
a
highly efficient  
synchronous step down dc-dc converter optimized for  
battery powered portable applications. It provides up  
to 1000-mA output current from a single Li-Ion cell.  
VIN Range From 2.3 V to 6 V  
2.25 MHz Fixed Frequency Operation  
Power Save Mode at Light Load Currents  
Output Voltage Accuracy in PWM mode ±1.5%  
Fixed Output Voltage Options  
With an input voltage range of 2.3 V to 6 V, the  
device supports batteries with extended voltage  
range and are ideal to power portable applications  
like mobile phones and other portable equipment.  
Typ. 15-µA Quiescent Current  
The TPS6229x operates at 2.25-MHz fixed switching  
frequency and enters Power Save Mode operation at  
light load currents to maintain high efficiency over the  
entire load current range.  
100% Duty Cycle for Lowest Dropout  
Voltage Positioning at Light Loads  
Available in a 2 × 2 × 0,8 mm SON Package  
The Power Save Mode is optimized for low output  
voltage ripple. For low noise applications, the device  
can be forced into fixed frequency PWM mode by  
pulling the MODE pin high. In the shutdown mode,  
the current consumption is reduced to less than 1 µA.  
The TPS6229x allows the use of small inductors and  
capacitors to achieve a small solution size.  
APPLICATIONS  
Cell Phones, Smart-phones  
WLAN  
PDAs, Pocket PCs  
Low Power DSP Supply  
Portable Media Players  
POL  
The TPS6229x is available in a 2-mm × 2-mm 6-pin  
SON package.
