3 Description

The LMZM33602 power module is an easy-to-use

integrated power solution that combines a 2-A, stepdown,

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.
