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.
