10A SIMPLE SWITCHER® Power Module with 2.95V-17V Input in QFN package with Current Sharing - LMZ31710

LMZ31710 (ACTIVE)

10A SIMPLE SWITCHER® Power Module with 2.95V-17V Input in QFN package with Current Sharing

Description

The LMZ31710 SIMPLE SWITCHER 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 10x10x4.3 mm QFN package is easy to solder onto a printed circuit board and allows a compact point-of-load design. 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.
