FEATURES
DESCRIPTION
Qualified for Automotive Applications
High Efficiency Step Down Converter
The TPS6229x-Q1 is a highly efficient synchronous
step
down
dc-dc
converters
optimized
for
Output Current up to 1000 mA
battery-powered portable applications. TPS6229x-Q1
VIN Range From 2.3 V to 6 V
provides up to 1000-mA output current from a single
2.25 MHz Fixed Frequency Operation
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
range and are ideal to power portable applications
Fixed Output Voltage Options
like mobile phones and other portable equipment.
Typ. 15-mA Quiescent Current

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 mA.
The TPS6229x-Q1 allows the use of small inductors
and capacitors to achieve a small solution size.
The TPS6229x-Q1 is available in a 2-mm × 2-mm
6-pin SON package.
