Product details

4 MHz switching — what it buys the layout

The TPS62801YKAR is a step-down buck converter that switches at 4 MHz. That frequency lets the designer use small-value inductors and ceramic capacitors.

1 A output and adjustable rail — BOM-fit check

Rated for 1 A continuous output with a positive adjustable output from 0.8 V to 1.55 V.

The base product number TPS62801 covers multiple output voltage options in the same DSBGA footprint, so a BOM-line change to a sibling variant does not require a board spin.

DSBGA package — what the rework bench needs to know

6-bump DSBGA, 1.05x0.70 mm.

Frequently asked questions

What is the datasheet for TPS62801YKAR?

Design engineers need full specs (pinout, electrical characteristics) to validate fit in their circuit.

What is the price of TPS62801YKAR?

Sourcing buyers need instant cost to compare against alternatives and stay within budget.

Is TPS62801YKAR in stock today?

Buyers must know immediate availability to avoid production delays; out-of-stock prompts search for substitutes.

What is the replacement for TPS62801YKAR?

If the part is out of stock or EOL, maintenance techs and brokers need a drop-in alternate quickly.

What is the output voltage range of TPS62801YKAR?

Designers need to confirm adjustable output limits to meet their specific voltage rail requirement.

Is TPS62801YKAR active or obsolete?

Brokers and long-term buyers need lifecycle status to decide if the part is safe to design in or needs a last-time buy.
