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.

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.
