Industry’s smallest 10-A power module features 95% efficiency

The 10-A LMZ31710, 7-A LMZ31707 and 4-A LMZ31704 power management modules are the latest members of the Simple Switcher family. The 10-A LMZ31710 module provides the industry’s highest power efficiency in the smallest package, up to 50% smaller than similar solutions. The power modules drive power-dense designs for industrial, communications infrastructure, medical, and test and measurement applications.

The power modules combine a dc/dc converter with power MOSFETs, a shielded inductor and passives into a QFN package. The modules combine the power efficiency of a synchronous switching regulator at greater than 95% with a linear regulator, while eliminating loop compensation design, inductor selection and complex layout placement challenges. Each device is pin-to-pin compatible and features soft-start pins, and current sharing for scalability from 4 to 60 A.
