3 Description
The LMZM33602 power module is an easy-to-use
integrated power solution that combines a 2-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, overcurrent and
overtemperature protections, make the LMZM33602
an excellent device for powering a wide range of
applications.
