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