3 Description
The TPS6208x devices are a family of high frequency
synchronous step down converters. With an input
voltage range of 2.3 V to 6 V, common battery
technologies are supported. Alternatively, the device
can be used for low voltage system power rails.
The TPS6208x focuses on high efficiency 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. This function, enabled by the
MODE pin, increases the run-time of battery driven
applications and keeps the standby current at its
lowest level to meet green energy standards targeting
a low stand-by current.
To address the requirements of system power rails,
the internal loop compensation allows a large
selection of external output capacitor values in
excess of 100 μF. With its DCS-Control™
architecture, excellent load transient performance and
output voltage regulation accuracy is achieved. The
device is available in 2-mm × 2-mm WSON package
with Thermal PAD.
