TDK Announce World's First IC Embedded Power Management Module For Smartphones And Tablets

In combination with newly developed surface-mounted capacitors and power inductors, this results in a space-saving footprint that is up to 60 percent smaller than discrete solutions. The highly integrated module offers advanced multi-channel power management capabilities in a single miniature package with dimensions of only 11.0mm x 11.0 mm x 1.6 mm.

The major features of the new power management module are its high-efficiency step-down converter power supply in a 5-channel configuration with a maximum output of 2.6 A, and its low-noise, low-loss voltage regulator power supply for up to 23 channels. A highly efficient lithium-ion secondary battery charging circuit is also included. Thanks to the fact that the IC completely embedded in the miniature three-dimensional SESUB structure, the power management module features superior thermal attributes compared with solutions with discrete packaged ICs. The module also offers greatly improved EMC performance due to the self-shielding effect of its design.

The new series meets the emerging needs for miniaturized multifunctional power management modules able to provide all of the functions in a smartphone with exactly the right amount of power, thus contributing to longer battery life.

Glossary:
