TPS84259 Overview
The TPS84259 is an easy-to-use negative output voltage power module that bines 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 ponents and eliminates the loop pensation and magnetics part selection process. The 9 × 11 × 2.8 mm QFN package is easy to solder onto a printed circuit board.
