Description for the LMZM33603
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.
