FEATURES
DESCRIPTION
DCS-ControlTM Architecture for Fast Transient
The TPS6208x devices are a family of high frequency
Regulation
synchronous step down converters. With an input
Snooze Mode for 6.5
A Ultra Low Quiescent
voltage range of 2.3V to 6.0V, common battery
Current
technologies are supported. Alternatively, the device
2.3V to 6.0V Input Voltage Range
can be used for low voltage system power rails.
Supports High Output Capacitance up to
The TPS6208x focuses on high efficient step down

F
conversion over a wide output current range. At
medium to heavy loads, the converter operates in
100% Duty Cycle for Lowest Dropout
PWM mode and automatically enters Power Save

driven applications and keeps the standby current at
its lowest level to meet green energy standards
targeting for a low stand-by current.
APPLICATIONS
To address the requirements of system power rails,
Battery Powered Portable Devices
the internal compensation circuit allows a large

from 10
F 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 with Thermal PAD.
