3 Description

The TPS6216x device family are easy to use

synchronous step-down DC/DC converters optimized

for applications with high power density. A high

switching frequency of typically 2.25 MHz 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.

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 battery as well

as from 12-V intermediate power rails. It supports up

to 1-A continuous output current at output voltages

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

Power sequencing is also possible by configuring the

enable and open-drain power good pins.

In power save mode, the devices show 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 shutdown current consumption is less than 2 μA.

The device, available in adjustable and fixed output

voltage versions, is packaged in an 8-pin WSON

package measuring 2.00 mm × 2.00 mm (DSG) or 8-

pin VSSOP package measuring 3.00 mm x 3.00 mm

(DGK).
