3 Description

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 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.
