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.
