FEATURES

DESCRIPTION

The TPS6215X family is an easy to use synchronous

•

DCS-Control^TMTopology

step down DC-DC converter optimized for

applications with high power density. A high switching

frequency of typically 2.5MHz allows the use of small

inductors and provides fast transient response as well

as high output voltage accuracy by utilization of the

DCS-Control™ topology.

Input Voltage Range: 3 to 17V

Up to 1A Output Current

Adjustable Output Voltage from 0.9 to 6V

Pin-Selectable Output Voltage (nominal, + 5%)

Programmable Soft Start and Tracking

Seamless Power Save Mode Transition

Quiescent Current of 17µA (typ.)

Selectable Operating Frequency

Power Good Output

With its wide operating input voltage range of 3V to

17V, the devices are ideally suited for systems

powered from either a Li-Ion or other batteries as well

as from 12V intermediate power rails. It supports up

to 1A continuous output current at output voltages

between 0.9V and 6V (with 100% duty cycle mode).

100% Duty Cycle Mode

The output voltage startup 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 and open-drain Power Good pins.

Short Circuit Protection

Over Temperature Protection

Available in a 3 × 3 mm, QFN-16 Package

APPLICATIONS

In Power Save Mode, the devices show quiescent

current of about 17μA 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 2μA.
