2.95V to 17V, 10A Step-Down Power Module with Current Sharing in 10x10x4.3mm QFN Package - LMZ31710
 

Description

The LMZ31710 power module is an easy-to-use integrated power solution that combines a 10-A DC/DC converter with power MOSFETs, a shielded inductor, and passives into a low-profile QFN package. This total power solution allows as few as three external components and eliminates 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 and allows a compact point-of-load design. The device achieves greater than 95% efficiency and excellent power dissipation capability with a thermal impedance of 13.3°C/W. The LMZ31710 offers the flexibility and the feature set of a discrete point-of-load design and is ideal for powering a wide range of ICs and systems. Advanced packaging technology affords a robust and reliable power solution compatible with standard QFN mounting and testing techniques.
