The LMZ31704RVQT power module is an easy-to-use integrated power solution that combines a 4-ADC/DC converter with power MOSFETs, a shielded inductor, and passives into a low profile, QFNpackage. This total power solution allows as few as three external components and eliminates theloop compensation and magnetics part selection process.
The 10 × 10 × 4.3 mm QFN package is easy to solder onto a printed circuit board andallows a compact point-of-load design. Achieves greater than 95% efficiency and excellent powerdissipation capability with a thermal impedance of 13.3°C/W. The LMZ31704RVQT offers the flexibilityand the feature-set of a discrete point-of-load design and is ideal for powering a wide range ofICs and systems. Advanced packaging technology affords a robust and reliable power solutioncompatible with standard QFN mounting and testing techniques.
