What technologies are enabling greater density?

Board area and height are becoming limiting factors as power demands increase. Power designers must squeeze more circuitry into their applications to differentiate their products while also increasing efficiency and enhancing thermal performance. Higher power levels in smaller form factors are now possible using TI’s advanced process, packaging and circuit-design technologies.

Understanding the Trade-Offs and Technologies to Increase Power Density

Space is limited in power-supply designs, and engineers face constant pressure to do more with less. The need for improved power density is clear, but what limits designers from increasing power density today? In this paper, we examine the barriers in depth and provide technology examples to help you overcome them.

Benefits of TI technologies for power density


Smaller footprint, less heat

Save board space with high-performance device options that pair unique integration techniques and ultra-low RDSON, low-RSP FETs for smaller die sizes.


Improved thermal performance

Remove heat from the package with advanced cooling technologies, including enhanced HotRod™ QFN packaging, power wafer chip-scale packaging (WCSP) and top-side cooling.


Increased efficiency

Use smaller passives while switching at higher frequencies – without sacrificing efficiency – with multilevel converter topologies and advanced power-stage gate drivers.

Three ways to overcome thermal challenges

From circuit design to packaging R&D, thermally optimized system designs and more, TI is your partner in solving power density challenges. Learn more about our multi-faceted approach to making smaller, higher performance ICs a reality.
