3 Description
The LMZ35003 power module is an easy-to-use
integrated power solution that combines a 2.5-A
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 small 9 mm × 11 mm × 2.8 mm, QFN package is
easy to solder onto a printed circuit board and allows
a compact point-of-load design with greater than 90%
efficiency and excellent power dissipation capability.
The LMZ35003 offers the flexibility and the featureset
of a discrete point-of-load design and is ideal for
powering a wide range of ICs and systems.
Advanced packaging technology affords a robust and
reliable power solution compatible with standard QFN
mounting and testing techniques.
