3 Description

The LMZ34002 SIMPLE SWITCHER® power module

is an easy-to-use, negative output voltage power

module that combines a 15-W DC-DC converter with

a shielded 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 9×11×2.8 mm QFN package is easy to solder

onto a printed circuit board and allows a compact

design with fewer components and excellent power

dissipation capability. The LMZ34002 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.
