Texas Instruments  TPS84259RKGT

The TPS84259 is an easy-to-use negative output voltage power module that combines a 15-WDC/DC converter with an inductor, and passives into a low-profile QFN package. This total powersolution allows as few as five external components and eliminates the loop compensation andmagnetics part selection process.

The 9 × 11 × 2.8 mm QFN package is easy to solder onto a printed circuit board. Itscompact 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 forpowering a wide range of ICs and analog circuits requiring a negative output voltage. Advancedpackaging technology affords a robust and reliable power solution, compatible with standard QFNmounting and testing techniques.
