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.
