Texas Instruments  LMZ31704RVQT

The LMZ31704 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 10x10x4.3 mm QFN package is easy to solder onto a printed circuit board and allows acompact point-of-load design. Achieves greater than 95% efficiency and excellent power dissipationcapability with a thermal impedance of 13.3°C/W. The LMZ31704 offers the flexibility and thefeature-set of a discrete point-of-load design and is ideal for powering a wide range of ICs andsystems. Advanced packaging technology affords a robust and reliable power solution compatible withstandard QFN mounting and testing techniques.
