3 Description

The TPS62134x family of devices is an easy-to-use,

synchronous step-down DC-DC converter, compatible

with Intel Skylake platform applications such as

Ultrabooks™ and notebooks. The high performance

DCS-Control™ architecture provides fast transient

response as well as high output voltage accuracy.

With a wide operating input-voltage range of 3 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. The devices have a

low-power mode where the output voltage is reduced

by using the LPM pin. In addition, the devices support

dynamic output-voltage change by using the VIDx

pins. The LPM and VIDx pins help the system

minimize power consumption in different operating

modes.

The output-voltage startup ramp is controlled by the

SS pin. The power sequencing is configurable by the

enable (EN) and power good (PG) pins. In powersave

mode, the devices show quiescent current of

approximately 20 μA which maintains high efficiency

over the entire load range. Short circuit protection

and thermal shutdown protect the IC and external

components from heavy current when the output is

shorted to ground. The device is available in a 3-mm

× 3-mm 16-pin VQFN package with thermal pad.
