DESCRIPTION
The TPS6229x device is a highly efficient
synchronous step down dc-dc converter optimized for
battery powered portable applications. It provides up
to 1000-mA output current from a single Li-Ion cell.
With an input voltage range of 2.3 V to 6 V, the
device supports batteries with extended voltage
range and are ideal to power portable applications
like mobile phones and other portable equipment.
The TPS6229x operates at 2.25-MHz fixed switching
frequency and enters Power Save Mode operation at
light load currents to maintain high efficiency over the
entire load current range.
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,
the current consumption is reduced to less than 1 µ A.
The TPS6229x allows the use of small inductors and
capacitors to achieve a small solution size.
The TPS6229x is available in a 2-mm × 2-mm 6-pin
SON package.
