DESCRIPTION
The LMZ30606 SIMPLE SWITCHER® power module
is an easy-to-use integrated power solution that
combines a 6-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 6-A rated output current at
85°C ambient temperature without airflow.
The LMZ30606 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.
