The TPS6229x devices are highly efficient synchronous step down
DC/DC convertersoptimized for battery powered portable
applications. They provide up to 1000-mA output current froma
single Li-ion cell.
With an input voltage range of 2.3 V to 6.0 V, the devices support
batteries withextended voltage range and are ideal to power
portable applications like mobile phones and otherportable
equipment.
The TPS6229x devices operate at 2.25-MHz fixed switching frequency
and enter power savemode operation at light load currents to
maintain high efficiency over the entire load currentrange.
The power save mode is optimized for low output voltage ripple. For
low noiseapplications, the devices can be forced into fixed
frequency pulse width modulation (PWM) mode bypulling the MODE pin
high. In the shutdown mode, the current consumption is reduced to
less than1 µA. The TPS6229x devices allow the use of small
inductors and capacitors to achieve a smallsolution size.
The TPS6229x devices operate over a free air temperature range of
–40°C to 85°C. Thedevices are available in a 2-mm × 2-mm 6-pin WSON
package (DRV).
