3 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.

With their 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).

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.

In power save mode, the devices draw quiescent

current of about 17 μA from VIN. Power Save Mode,

entered automatically and seamlessly if the load is

small, maintains high efficiency over the entire load

range. In Shutdown Mode, the device is turned off and

current consumption is less than 2 μA.

The device, available in adjustable and fixed output

voltage versions, is packaged in a 16-pin VQFN

package measuring 3 mm × 3 mm (RGT).
