High Efficiency Step-Down Converter
Output Current up to 600 mA
The
TPS62260
device
is
a
highly
efficient
synchronous step down dc-dc converter optimized for
VIN Range from 2 V to 6 V for Li-ion Batteries
battery powered applications. It provides up to
with Extended Voltage Range
600-mA output current from a single Li-Ion cell and is
2.25 MHz Fixed Frequency Operation
ideal to power mobile phones and other portable
Power Save Mode at Light Load Currents
applications.
Output Voltage Accuracy in PWM mode
±1.5%
With an wide input voltage range of 2 V to 6 V, the
device supports applications powered by Li-Ion
Typ. 15
μA Quiescent Current
batteries with extended voltage range, two and three
100% Duty Cycle for Lowest Dropout

rails.
Voltage Positioning at Light Loads
The TPS62260 operates at 2.25 MHz fixed switching
Available in a small 2
×2×0.8mm QFN and
frequency and enters Power Save Mode operation at
TSOT-23 package
light load currents to maintain high efficiency over the
entire load current range.
Allows
<1mm Solution Height
The Power Save Mode is optimized for low output
APPLICATIONS
voltage ripple. For low noise applications, the device
can be forced into fixed frequency PWM mode by
PDAs, Pocket PCs
pulling the MODE pin high. In the shutdown mode,
Low Power DSP Supply
the current consumption is reduced to less than 1
μA.
Portable Media Players
TPS62260 allows the use of small inductors and
POL applications
capacitors to achieve a small solution size.
The TPS62260 is available in a very small 2
×2 6 pin
QFN and TSOT-23 5 pin package.
