The LMZ30604 power module is an easy-to-use integrated power solution that combines a 4-A DC/DC converter with power MOSFETs, a shielded inductor, and passives into a low profile, QFN package. This total power solution requires as few as 3 external components and eliminates the loop compensation and magnetics part selection process.

The 9×11×2.8 mm QFN package is easy to solder onto a printed circuit board and allows a compact point-of-load design with greater than 90% efficiency and excellent power dissipation with a thermal impedance of 12°C/W junction to ambient. The device delivers the full 4-A rated output current at 85°C ambient temperature without airflow.

The LMZ30604 offers the flexibility and the feature-set of a discrete point-of-load design and is ideal for powering performance DSPs and FPGAs. Advanced packaging technology afford a robust and reliable power solution compatible with standard QFN mounting and testing techniques.
