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.
