3 Description

The TPS6216x-Q1 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 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 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 draw quiescent

current of about 17 μA from VIN. Power Save Mode,

entered automatically and seamlessly if 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 devices are available in adjustable and fixed

output voltage versions and are packaged in an 8-pin

WSON package measuring 2 × 2 mm (DSG).
