FEATURES  
DESCRIPTION  
High Efficiency Step Down Converter  
Output Current up to 400 mA  
The TPS62270 device is  
a
high efficiency  
synchronous step down DC-DC converter optimized  
for battery powered portable applications. It provides  
up to 400 mA output current from a single Li-Ion cell.  
VIN Range From 2.0V to 6V for Li-Ion Batteries  
With Extended Voltage Range  
2.25 MHz Fixed Frequency Operation  
Pin-Selectable Fixed Output Voltage  
Power Save Mode for Highest Efficiency  
With an input voltage range of 2.0 V to 6 V the device  
supports Li-Ion batteries with extended voltage range,  
and is ideal to power portable applications like mobile  
phones and other portable equipment.  
Automatic transition between PFM and PWM  
Mode  
The TPS62270 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. The Power Save Mode is  
optimized for low output voltage ripple.  
Output Voltage Accuracy in PWM Mode ±1.5%  
Voltage Positioning in PFM Mode  
Typical 15-µA Quiescent Current  
100% Duty Cycle for Lowest Dropout  
Available in 2×2×0,8 mm SON Package  
Allows <1 mm Solution Height  
With the VSEL pin, two different fixed output voltages  
can be selected. This function features a dynamic  
voltage scaling for low power processor cores.  
In the shutdown mode, the current consumption is  
reduced to less than 1µA. TPS62270 allows the use  
of small inductors and capacitors to achieve a small  
solution size.  
APPLICATIONS  
Low Power Processor Supply  
Cell Phones, Smart-phones  
Navigation Systems  
Low Power DSP Supply  
Portable Media Players  
Digital Cameras  
The TPS62270 is available in a 2 mm × 2 mm, 6-pin  
SON package.
