LMZ31710RVQR Texas Instruments MCU

LMZ31710RVQR Overview

The LMZ31710 power module is an easy-to-use integrated power solution that combines a10-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 10 × 10 × 4.3 mm QFN package is easy to solder onto a printed circuit board andallows a compact point-of-load design. The device achieves greater than 95% efficiency andexcellent power dissipation capability with a thermal impedance of 13.3°C/W. The LMZ31710 offersthe flexibility and the feature set of a discrete point-of-load design and is ideal for powering awide range of ICs and systems. Advanced packaging technology affords a robust and reliable powersolution compatible with standard QFN mounting and testing techniques.
