 and multiphase controller product lines.  We introduced higher voltage drivers to expand success beyond PCs to motor drive applications such as power tools and garden equipment.  We have also made a major investment in R&D to enter the multiphase controller market in 2020 with the introduction of the Intel IMVP 9.1 controller for notebooks.  Since then, AOS has released or is designing in several multiphase controller families serving Intel, AMD and NVIDIA.  Introduction of these multiphase controllers has enabled AOS to become a complete solution level provider, across multiple compute platforms from PCs, graphics cards to AI and datacenter.

The following table lists our product families and the principal end uses of our products:

Power discrete products

Power discretes are used across a wide voltage and current spectrum, requiring high efficiency and reliability under harsh conditions.  Due to the diverse nature of end-market applications, we market both general purpose MOSFETs that are used in multiple applications as well as application specific MOSFETs.

Our current power discrete product line includes industry standard trench MOSFETs, Shielded-Gate low voltage and mid-voltage MOSFETs, SuperJunction high voltage MOSFETs, and trench-stop IGBTs, as well as application specific MOSFETs for smartphone battery management, dual MOSFETs
