TPS6215xA-Q1 3V to 17-V 1A Step-Down Converter with DCS-Control^TM

1 Features

3 Description

The TPS62150A-Q1 device 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

through the use of the DCS-Control™ topology.

DCS-Control™ Topology

•

Qualified for Automotive Applications

AEC-Q100 Qualified With the Following Results:

–

Device Temperature Grade: –40°C to 125°C

Operating Junction Temperature Range

–

Device HBM ESD Classification Level H2

Device CDM ESD Classification Level C4B

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

V, the device is ideally suited for systems powered

from intermediate bus power rails. The device

supports up to 1A continuous output current at output

voltages between 0.9 V and 6 V (with 100% duty

cycle mode).

•

Input Voltage Range: 3 to 17V

Adjustable Output Voltage from 0.9 to 6V

Pin-Selectable Output Voltage (nominal, + 5%)

Programmable Soft Start and Tracking

Seamless Power Save Mode Transition

Quiescent Current of 17µA (typ.)

Power Good Output

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.

100% Duty Cycle Mode

Short Circuit Protection

In power save mode, the device shows quiescent

current of about 17 μA from V_IN. Power save mode

which is 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 is packaged in a 16-pin VQFN

package measuring 3 × 3 mm (RGT).

Over Temperature Protection

Available in a 3 × 3 mm, VQFN-16 Package
