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
V
IN Range From 2V to 6V for Li-Ion Batteries
for battery powered portable applications. It provides
With Extended Voltage Range
up to 400 mA output current from a single Li-Ion cell.
2.25 MHz Fixed Frequency Operation
With an input voltage range of 2 V to 6 V the device
Pin-Selectable Fixed Output Voltage
supports Li-Ion batteries with extended voltage range,
Power Save Mode for Highest Efficiency
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
Voltage Positioning in PFM Mode
frequency and enters Power Save Mode operation at
light load currents to maintain high efficiency over the
Typical 15-A Quiescent Current
entire load current range. The Power Save Mode is
100% Duty Cycle for Lowest Dropout
optimized for low output voltage ripple.
Available in 2×2×0,8 mm SON Package
With the VSEL pin, two different fixed output voltages
Allows <1 mm Solution Height
can be selected. This function features a dynamic
voltage scaling for low power processor cores.
In the shutdown mode, the current consumption is
Low Power Processor Supply
reduced to less than 1
A. TPS62270 allows the use
Cell Phones, Smart-phones
of small inductors and capacitors to achieve a small
Navigation Systems
solution size.
Low Power DSP Supply
The TPS62270 is available in a 2 mm × 2 mm, 6-pin
Portable Media Players
SON package.
