3 DESCRIPTION

The TPS84259 is an easy-to-use negative output

voltage power module that combines a 15-W DC/DC

converter with an inductor, and passives into a lowprofile

QFN package. This total power solution allows

as few as five external components and eliminates

the loop compensation and magnetics part selection

process.

The 9 × 11 × 2.8 mm QFN package is easy to solder

onto a printed circuit board. Its compact design also

contains fewer components and possesses excellent

power dissipation capability. The TPS84259 offers

the flexibility and the feature-set of a discrete design

and is ideal for powering a wide range of ICs and

analog circuits requiring a negative output voltage.

Advanced packaging technology affords a robust and

reliable power solution, compatible with standard

QFN mounting and testing techniques.
