3 Description
The TPS6223x device family is a high-frequency,
synchronous, step-down DC – DC converter
optimized for battery powered portable applications. It
supports up to 500-mA output current and allows the
use of tiny and low-cost chip inductors and
capacitors.
With a wide input voltage range of 2.05 V to 6 V, the
device supports applications powered by Li-Ion
batteries with extended voltage range. The minimum
input voltage of 2.05 V allows as well the operation
from Li-primary or two alkaline batteries. Different
fixed output voltage versions are available from 1.0 V
to 3.3 V.
The TPS6223x series features switch frequency up to
3.8 MHz. At medium to heavy loads, the converter
operates in pulse width modulation (PWM) mode and
automatically enters power-save mode operation at
light load currents to maintain high efficiency over the
entire load current range.
Because of its excellent power supply rejection ratio
(PSRR) and AC load regulation performance, the
device is also suitable to replace linear regulators to
obtain better power conversion efficiency.
The power-save mode in TPS6223x reduces the
quiescent current consumption down to 22 μA during
light load operation. It is optimized to achieve very
low output voltage ripple even with small external
component and features excellent AC load regulation.
For very noise-sensitive applications, the device can
be forced to PWM mode operation over the entire
load range by pulling the MODE pin high. In the
shutdown mode, the current consumption is reduced
to less than 1 μA. The TPS6223x operates over a
junction temperature range of –40°C to 125°C. It is
available in a 1 mm × 1.5 mm × 0.6 mm 6-pin SON
package.
