3 Description

The TPS6213x family are easy-to-use synchronous

step down DC-DC converters optimized for

applications with high power density. A high switching

frequency of typically 2.5 MHz allows the use of small

inductors and provides fast transient response as well

as high output voltage accuracy by use of the DCSControl

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. They

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 start-up ramp is

controlled by the soft-start pin, which allows operation

as either a stand-alone 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 draw quiescent

current of approximately 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 a 16-pin VQFN

package measuring 3 mm × 3 mm (RGT).
