3 Description

The LMZ31506 power module is an easy-to-use

integrated power solution that combines a 6-A DC-to-

DC converter with power MOSFETs, a shielded

inductor, and passives into a low profile, QFN

package. This total power solution allows as few as

three external components and eliminates the loop

compensation and magnetics part selection process.

The 9×15×2.8 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 13°C/W junction to ambient. The

device delivers the full 6-A rated output current at

85°C ambient temperature without airflow.

The LMZ31506 offers the flexibility and the featureset

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.
