3 Description
The LMZM33603 power module is an easy-to-use
integrated power solution that combines a 3-A, step-
down, DC/DC converter with power MOSFETs, a
shielded inductor, and passives into a low-profile
package. This power solution requires as few as four
external
components
and
eliminates
the
loop
compensation and magnetics part selection from the
design process.
The 9 mm × 7 mm × 4 mm 18-pin, QFN package is
easy to solder onto a printed circuit board and allows
a compact, low-profile, point-of-load design. The full
feature set, including power good, programmable
UVLO, prebias start-up, and overcurrent and over-
temperature protection, make the LMZM33603 an
excellent device for powering a wide range of
applications.
