Texas Instruments  LMZ31707RVQR

The LMZ31707 SIMPLE SWITCHER® power module is an easy-to-use integrated power solutionthat combines a 7-A DC-DC converter with power MOSFETs, a shielded inductor, and passives into alow profile, QFN package. This total power solution allows as few as three external components andeliminates the loop 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 LMZ31707 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.
