TPS6282x 2.4-V to 5.5-V Input, 1-, 2-, 3-, 4-A Step-down Converter with 1% Output

Accuracy in 1.5-mm × 1.5-mm QFN Package

1 Features

3 Description

•

Available as an integrated-inductor power module:

TPSM82821 and TPSM82822

DCS-Control^™topology

1% feedback or output voltage accuracy (full

temperature range)

Up to 97% efficiency

26-mΩ and 25-mΩ internal power MOSFETs

2.4-V to 5.5-V input voltage range

4-μA operating quiescent current

2.2-MHz switching frequency

Adjustable output voltage from 0.6 V to 4 V

Power save mode for light load efficiency

100% duty cycle for lowest dropout

Active output discharge

Power good output

Thermal shutdown protection

Hiccup short-circuit protection

A forced-PWM version for CCM operation

Create a custom design using the TPS6282x with

the WEBENCH^®Power Designer

The TPS6282x is an easy-to-use synchronous step-

down DC-DC converters family with a very low

quiescent current of only 4 μA. Based on the DCS-

Control topology, it provides a fast transient response.

The internal reference allows to regulate the output

voltage down to 0.6 V with a high feedback voltage

accuracy of 1% over the junction temperature range

of –40°C to 125°C. The family devices are pin-to-pin

and BOM-to-BOM compatible. The entire solution

requires a small 470-nH inductor, a single 4.7-µF

input capacitor and two 10-µF or single 22-µF output

capacitor.

•

The TPS6282x is available in two flavors. The first

includes an automatically entered power save mode

to maintain high efficiency down to very light loads for

extending the system battery run-time. The second

runs in forced-PWM maintaining

continuous

conduction mode to ensure the least ripple in the

output voltage and a quasi-fixed switching frequency.

The device features a Power Good signal and an

internal soft start circuit. It is able to operate in 100%

mode. For fault protection, it incorporates a HICCUP

short circuit protection as well as a thermal shutdown.

The device is available in a 6-pin 1.5 x 1.5-mm QFN

package, offering the highest power density solution.
