synchronous step down converters. With an input
voltage range of 2.3V to 6.0V, common battery
technologies are supported. Alternatively, the device
can be used for low voltage system power rails.

The TPS6208x focuses on high efficient step down
conversion over a wide output current range. At
medium to heavy loads, the converter operates in
PWM mode and automatically enters Power Save
Mode operation at light load currents to maintain high
efficiency over the entire load current range. To
maintain high efficiency at very low load or no load
currents, a Snooze Mode with an ultra low quiescent
current is implemented, that is enabled by the Mode
pin. This function increases the run-time of battery
driven applications and keeps the standby current at
its lowest level to meet green energy standards
targeting for a low stand-by current.
Supports High Output Capacitance up to
100µF

To address the requirements of system power rails,
the internal compensation circuit allows a large
selection of external output capacitor values ranging
from 10µF up to 100uF effective capacitance. With its
DCS-ControlTM architecture excellent load transient
performance and output voltage regulation accuracy
is achieved. The device is available in 2x2mm SON
package and VSSOP package with Thermal PAD.
