Texas Instruments  LMZ31520RLGT

The LMZ31520 power module is an easy-to-use integrated power solution that combines a20-A DC-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 15×16×5.8 mm QFN package is easy to solder onto a printed circuit board and allows acompact point-of-load design. Achieves greater than 95% efficiency, has ultra-fast load stepresponse and excellent power dissipation capability with a thermal impedance of 8.6°C/W. TheLMZ31520 offers the flexibility and the feature-set of a discrete point-of-load design and is idealfor powering a wide range of ICs and systems. Advanced packaging technology affords a robust andreliable power solution compatible with standard QFN mounting and testing techniques.
