FEATURES  
DESCRIPTION  
The TPS6214X family is an easy-to-use synchronous  
step-down dc-dc converter optimized for applications  
with high power density. A high switching frequency  
of typically 2.5 MHz allows the use of small inductors  
and provides fast transient response by use of the  
DCS-Control™ topology.

DCS-ControlTM Topology  
Input Voltage Range: 3 V to 17 V  
Up to 2-A Output Current  
Adjustable Output Voltage from 0.9 V to 6 V  
Pin-Selectable Output Voltage (Nominal, +5%)  
Programmable Soft Start and Tracking  
Seamless Power-Save Mode Transition  
Quiescent Current of 17 µA (typ.)  
Selectable Operating Frequency  
Power-Good Output  
With its wide operating input voltage range of 3 V to  
17 V, the devices are ideally suited for systems  
powered from either a Li-Ion or other batteries, as  
well as from 12-V intermediate power rails. It  
supports up to 2 A of continuous output current at  
output voltages between 0.9 V and 6 V (with 100%  
duty-cycle mode).  
100% Duty-Cycle Mode  
The output voltage start-up ramp is controlled by the  
soft-start pin, which allows operation as either a  
standalone power supply or in tracking configurations.  
Power sequencing is also possible by configuring the  
enable (EN) and open-drain power-good (PG) pins.  
Short-Circuit Protection  
Overtemperature Protection  
Available in a 3-mm × 3-mm, QFN-16 Package  
APPLICATIONS  
In power-save mode, the devices show quiescent  
current of about 17 μA from VIN. Power-save mode,  
entered automatically and seamlessly if load is small,  
maintains high efficiency over the entire load range.  
In shutdown mode, the device is turned off and  
shutdown current consumption is less than 2 μA.
