FEATURES
DESCRIPTION
Output Current up to 600 mA
The
TPS62560
device
is
a
high
efficiency
synchronous step down converter, optimized for
VIN Range from 2.5 V to 5.5 V
battery powered portable applications. It provides up
Output Voltage Accuracy in PWM Mode ±2.5%
to 1000-mA output current from batteries, such as
Typical 15-
μA Quiescent Current
single Li-Ion or other common chemistry AA and AAA
100% Duty Cycle for Lowest Dropout
cells.
Soft Start
With an input voltage range of 2.5 V to 5.5 V, the
device is targeted to power a large variety of portable
Available in a Small TSOT, and
handheld equipment or POL applications.
2 mm × 2 mm × 0.8 mm QFN Package
For Improved Features Set, see TPS62260
The TPS62560 family operates at 2.25-MHz fixed
switching frequency and enters a Power Save Mode
operation at light load currents to maintain a high
APPLICATIONS
efficiency over the entire load current range.
PDAs, Pocket PCs, Portable Media Players
Low-Power DSP Supply
The Power Save Mode is optimized for low output
voltage ripple. For low noise applications, the device
POL Applications
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 A.
The TPS62560 allows the use of small inductors and
capacitors to achieve a small solution size.
TPS62560 and TPS62562 are available in a 2-mm ×
2-mm,
6-terminal
QFN
package,
whereas
the
TPS62561 is available in a 5-terminal TSOT23
package.
