High Efficiency Step Down Converter
Output Current up to 600 mA
The TPS62260 device is a high efficient synchronous
step down dc-dc converter optimized for battery
Wide V
IN Range from 2 V to 6 V for Li-Ion
powered applications. It provides up to 600-mA
Batteries with Extended Voltage Range
output current from a single Li-Ion cell and is ideal to
2.25 MHz Fixed Frequency Operation
power mobile phones and other portable applications.
Power Save Mode at Light Load Currents
With an wide input voltage range of 2 V to 6 V, the
Output Voltage Accuracy in PWM mode ±1.5%
device supports applications powered by Li-Ion
batteries with extended voltage range, two and three
Typ. 15 A Quiescent Current
cell alkaline batteries, 3.3 V and 5 V input voltage
100% Duty Cycle for Lowest Dropout
rails.
Soft Start
The TPS62260 operates at 2.25 MHz fixed switching
Voltage Positioning at Light Loads
frequency and enters Power Save Mode operation at
Available in a small 2×2×0,8mm SON and
light load currents to maintain high efficiency over the
TSOT-23 package
entire load current range.
Allows <1mm Solution Height
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,
PDAs, Pocket PCs
the current consumption is reduced to less than 1
A.
Low Power DSP Supply
TPS62260 allows the use of small inductors and
Portable Media Players
capacitors to achieve a small solution size.
POL applications
The TPS62260 is available in a very small 2
×2 6 pin
SON and TSOT-23 5 pin package.
