3 Description

The

TPS6213XA-Q1

devices

are

easy-to-use

synchronous step-down DC-DC converters 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 as well as high output-voltage accuracy

through the use of the DCS-Control™ topology.

With a wide operating input-voltage range of 3 to 17

V, the devices are ideally suited for systems powered

from intermediate bus power rails. The devices

support up to 3-A continuous output current at output

voltages between 0.9 V and 6 V (with 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.

In power save mode, the devices show quiescent

which is entered automatically and seamlessly if the

load is small, maintains high efficiency over the entire

load range. In shutdown mode, the devices are

turned off and shutdown current consumption is less

than 2 μA. The devices are packaged in a 16-pin

VQFN package measuring 3 × 3 mm (RGT).
