3 Description

The TPS6215x 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 as well as high

output-voltage accuracy by the use of 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 Li-Ion or other batteries as well

as from 12-V intermediate power rails. The devices

support up to 1-A continuous output current at output

voltages between 0.9 V and 6 V (in 100% duty-cycle

mode). The soft-start pin controls the output-voltage

start-up ramp, 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 turns off and

current consumption is less than 2 μA.

The device, available in adjustable- and fixed-outputvoltage

versions, comes in a 16-pin VQFN package

measuring 3 × 3 mm (RGT).
