TDK acquires Faraday Semi LLC to bolster power solutions

  • TDK acquires Faraday Semi LLC, a developer of the world’s smallest class of Point of Load (μPOL™) solutions
  • TDK to further strengthen its power solutions business to become a leader in the power management market through expanded high-performance semiconductor technology, advanced packaging technology, and electronic components technologies
  • Acquisition enables TDK to deliver high-efficiency, high-performance, super-compact solutions catering to the new trend of miniaturization of power solutions for demanding applications in information and communication technology (ICT), and in industrial devices and automotive markets

May 9, 2018


TDK Corporation (TSE 6762, President and CEO: Shigenao Ishiguro, hereinafter “TDK”) announced that today TDK acquired Faraday Semi LLC (CEO: Parviz Parto, hereinafter “Faraday Semi”), a U.S.-based venture-backed company engaged in the design of advanced power semiconductor ICs. Faraday Semi is now a wholly owned subsidiary of TDK.

Faraday Semi, based in California, USA, is a fast-growing semiconductor company with innovations in systems solutions focused on power management through DC-DC power conversion. Faraday Semi solutions incorporate high performance semiconductor in advanced packaging technologies such as semiconductor embedded in substrate (SESUB) and advanced electronic components to achieve unique system integration in a smaller size and lower profile by 3D assembly. This integration allows TDK to deliver higher efficiency and ease of use at a lower total system cost to what is currently available today.

This results in the world’s smallest class of high power density Point of Load solutions (product brand: μPOL™). The continued popularization of “big data” usage is driving the rapidly increasing global demand for high density and highly efficient data center and reliable data storage, and these miniature devices provide high-performance solutions that meet the challenging requirements of modern digital ICs such as ASICs, FPGAs and CPUs. Their emphasis on high efficiency and thermal management makes these devices suitable for distributed power management systems including ICT and other applications.

This will enable TDK to deliver high-efficiency, high-performance, super-compact solutions catering to the evolving trend of miniaturized power solutions and their accompanying semiconductors. TDK is acquiring Faraday Semi in anticipation that these technologies will help to improve systems efficiency and reduce system costs for customers around the world, in ICT as well as in the industrial devices and automotive markets.

The following is an outline of the company profile:

  1. Company name: Faraday Semi LLC
  2. Location: California, USA
  3. Established: November 2015
  4. Founder and CEO: Parviz Parto
  5. Main business operations: Development and design of Power Semiconductor ICs.


  • μPOL™ : μPOL™ (micro point of load) is a DC - DC converter to be placed in the vicinity of complex ICs such as ASIC, FPGA etc. It is called Point of Load because it is placed in the vicinity, its abbreviation is called POL. By minimizing the distance between converter and IC, the resistance and the inductance components can be minimized, allowing fast response and accurate regulation with dynamic IC currents. (μPOL™ is a registered trademark of Faraday Semi LLC.)
