3 DESCRIPTION

The TPS84250 is an easy-to-use integrated power

solution that combines a 2.5-A DC/DC converter with

an inductor and passives into a low profile, QFN

package. This total power solution allows as few as

five external components and eliminates the loop

compensation and magnetics part selection process.

The small 9 mm × 11 mm × 2.8 mm, QFN package is

easy to solder onto a printed circuit board and allows

a compact point-of-load design with greater than 90%

efficiency and excellent power dissipation capability.

The TPS84250 offers the flexibility and the featureset

of a discrete point-of-load design and is ideal for

powering a wide range of ICs and systems.

Advanced packaging technology affords a robust and

reliable power solution compatible with standard QFN

mounting and testing techniques.
