FEATURES
DESCRIPTION
2 MHz / 3 MHz Switch Frequency
Up to 94% Efficiency
The TPS6223X device family is a high frequency
synchronous step down DC-DC converter optimized
Output Peak Current up to 500mA
for battery powered portable applications. It supports
Excellent AC and Transient Load Regulation
up to 500mA output current and allows the use of tiny
High PSRR (up to 90dB)
and low cost chip inductors and capacitors.
Small External Output Filter Components 1mH/
With a wide input voltage range of 2.05V to 6V the
4.7mF
device supports applications powered by Li-Ion
batteries with extended voltage range. The minimum
VIN range from 2.05V to 6V
input voltage of 2.05V allows as well the operation
Optimized Power Save Mode For Low Output
from Li-primary or two alkaline batteries. Different
Ripple Voltage
fixed output voltage versions are available from 1.0V
Forced PWM Mode Operation
to 3.3V.
Typ. 22 mA Quiescent Current
The TPS6223X series features switch frequency up
100% Duty Cycle for Lowest Dropout
to 3.8MHz. At medium to heavy loads, the converter
operates in PWM mode and automatically enters
Small 1 × 1.5 × 0.6mm3 SON Package
Power Save Mode operation at light load currents to
12 mm2 Minimum Solution Size
maintain high efficiency over the entire load current
Supports 0.6 mm Maximum Solution Height
range.
Soft Start with typ. 100ms Start Up Time
Because
of
its
excellent
PSRR
and
AC
load
regulation performance, the device is also suitable to
APPLICATIONS
replace linear regulators to obtain better power
LDO Replacement
conversion efficiency.
Portable Audio, Portable Media
The Power Save Mode in TPS6223X reduces the
Cell Phones
quiescent current consumption down to 22mA during
light load operation. It is optimized to achieve very
Low Power Wireless
low output voltage ripple even with small external
Low Power DSP Core Supply
component and features excellent ac load regulation.
Digital Cameras
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 1mA. The TPS6223X is available in a 1 ×
1.5mm2 6 pin SON package.
