Overview

The LMZ34002RKGR SIMPLE SWITCHER power module is an easy-to-use, negative output voltagepower module that combines a 15-W DC-DC converter with a shielded inductor, and passives into a lowprofile, QFN package. This total power solution allows as few as five external components andeliminates 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 and allows acompact design with fewer components and excellent power dissipation capability. The LMZ34002offers the flexibility and the feature-set of a discrete design and is ideal for powering a widerange of ICs and analog circuits requiring a negative output voltage. Advanced packaging technologyaffords a robust and reliable power solution compatible with standard QFN mounting and testingtechniques.
