3 Description

The LMZM33603 power module is an easy-to-use

integrated power solution that combines a 3-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, and overcurrent and overtemperature

protection, make the LMZM33603 an

excellent device for powering a wide range of

applications.
